One question though, why are you not considering the sludge from primary clarifier?
For this problem, the focus is on calculating the waste sludge flow rate (Q_w) associated with the secondary clarifier and aeration tank processes. The sludge from the primary clarifier is typically removed separately as "primary sludge" and is not mixed with the activated sludge in the secondary treatment system. If the problem required finding the total sludge flow rate from both the primary and secondary clarifiers, it would explicitly state something like: "Determine the total sludge flow rate (MGD)..."
Excellent Video. Been really impressed with this type of question. Hope I will get the similar questions for my PE later this month 🥲
Thank you! Keep working through lots of practice problems! Definitely focus on mastering the easier topics first, as it’s impossible to be an expert in every subject. In my opinion, you can completely bomb one topic and still pass! You’ve got this!
Absolutely spot-on video for my PE prep. Thanks!
I'm happy to know this helped! Thank you for practicing with me!
Can’t you just use the calculator to solve like you would an integral?
For a design of a retaining wall, which is a good result to be expected, the passive or the active Earth pressure?
Question. What type of retaining wall? Is the retaining wall allowed to move away from the soil? If so, the active case is ok but this assumes the wall moves a tiny bit away from the soil.
Sooo nice❤
This man is master of teaching engineering economics in a very understandable way. Kudos to you bro for making this video and helping thousands of aspiring engineers. I hope people recognizes you and your business blooms!
@@jaysonbolanos8063 I appreciate it man!!! This made my day. For real, it means so much to me to know I’m helping you master these analysis skills for your FE exam. Thank you so much for the best wishes and for this comment 🙏🏼
side questions? what would be a justification to neglect KE and PE on this problem aside the fact that the problem is telling you to neglect?
Hi Fernando! Good question! First of all, for this FE type question (basic fundamental question) since the does not provide information about changes in the velocity of the gas or the height of the system. Without these values, we cannot say the KE or PE changes are substantial enough. Also in a tight controlled unit like a piston-cylinder assembly, the motion of the gas and the piston is usually very small and very controlled. The gas particles inside the cylinder do not experience big changes in velocity or height therefore we can often assume changes in kinetic and potential energy negligible.
Thak you teacher
My pleasure!
This question dosent have word serach index , its confusing if you not said will be use William q.
The Hazen Williams equation applies in this case since the table for the Hazen Williams coefficients is given. I hope this makes sense.
This was very helpful, thank you.
@@silindilenkosi1355 you’re welcome !
great video! one question: why does the total head loss is 0? my understanding is the that head loss is from the friction, which cannot be recovered
is that because the direction of the headless? in the reference book "Multipath Pipeline Problems" section, the head loss in the parallel pipe with same flow direction pipes are equal. but in this question, they are reverse
Close! It's still true that the headloss of parallel pipes is the same. This concept should be remember when dealing with parallel pipes that start at the same junctoin (node) and end at the same junction (node). But why is the headloss equal to zero in a looped system? It all goes back to CONSERVATION OF ENERGY. In each closed water distribution loop, there can be no net gain or loss of energy (head). Imagine being a water particle going around the loop from the start to the end. You will end up where you started therefore the energy level must be the same. If we have a head loss in one pipe in the loop it must be balanced by energy head gains or losses in other pipes. This makes the total head loss around the loop equal to zero. For the water distriubtion system to be in equilibrium, each pipe path around the loop must have the same head loss, so there is no “extra” energy at any point. What we do in real life is adjust the flow distriubtion to ensure the head loss is equal to zero in a looped system. By applying the condition that the sum of head losses around each loop is zero, the iterative Hardy Cross method is applied to adjust the flow distribution in the network until all loops satisfy this balance. KEY WORD: ADJUST FLOW DISTRIUBTION. The flowrate into each junction will be different. But in the end, the headloss in one pipe is balance by the headloss in another.
While using the Casio fx115es, I went to DIST - BIONOMIAL CD - VARIABLE; then plug in P fail - 0.30, n - 8, X - 4 and I also got 0.94203. With the "at most" language, it would be a cumulative variable.
Good one!
is it T=39.2N?
That's right! Nice work!!!
have you heard of the PPI2Pass program to help with FE exams? if so, how similar are your questions to that of the PPI ones??
I don't know much about PPI especially for the Mechanical FE exam. They've been in this FE prep space for a long time now. Just make sure they have updated resources that cover the style of the latest 2024 FE exam which includes a balance of alternative type questions and the classic multiple choice questions.
how similar are your questions to that of the fe exam???
Older videos I have are good to cover for the basics. But newer videos are more similar to real FE problems you may see.
Excellent
Tricky problem with lot of good info.
What an impressive explanation 👏 👌
So, another way of doing first question and quicker is simply by finding the average pressure times the area of the door. Evarage pressure is ( (1500 x 9.8 x 8 meters above the door) + (1500 x 9.8 x 12 meters of total distance to the floor) ) divided by 2. You then multiply that times area ( 5 x 1 )m^2. You get the resultant force because F = Pressure times Area. It also works if the door in vertically positioned at 90 degrees. And if there is no wall above the door than is just the, simply just a door ((atmosphere pressure + density x g x distance of depth))/2 where the atmosphere pressure will be 0.
You are excellent explaining that! Thank you.
Thank you so much!
I failed for the 6th time. Im buying your program.
Hey! It's normal to fail this exam. All my students do before finally hitting the passing mark. Reflect on and learn from each failed attempt. Come up with a new game plan that will switch up your previous study techniques. Feel free to email me if you need help!
Where did you find MMC and LMC in the handbook? I didn't hear you mention the page number 8:55 and don't see your explanation in the handbook
check it in gd&t section which is right below the limit and fit
Best FE youtuber
holy smokes.. after 4 years of high school and 5.5 years of university.. i finally have a concrete answer and method to differentiate the two. Ive always struggled to understand when the switch occurred and the "why" behind it all. Thank you so much.
Haha, I loved reading this!!! I’m so glad this helped. Thank you 😊
Thank you
Im averafing around 68-70 percent .
Thanks helped a lot
Where in the handbook is the L.atm conversion to Joules? I don't see it on pg 3, only for the universal gas constants
We would need to convert L to cubic meters then atm to pascals separately then we would get joules. We are still using page.3 for convert these. 1 L = 0.001 cubic meters (m^3) 1 atm = 101328 pascals = 101326 N/m^2 Multiply the two: 1L - atm = 0.001 m^3 - 101326 N/m^2 = 101.328 N - m = 101.328 Joules
would we get a question this long on the FE exam knowing that there's so many questions and so little time???
@@farooquenadeem5300 Not this long. But definitely know the concept here.
If the aquifer doesn't have an uniform thickness, how do you calculate the area? Do you use an average thickness from different measurements along the aquifer?
love these explanations!🙏
More to come!
why is my approach wrong? on this diagram, 1 lies on the sat liquid region, we know that the pressure at 4 and 1 are same, so I find the hf at that place, given the h must stay constant, hf=h4, which is what the question is asking. but my answer of 419 kJ/kG isn't correct
if im not mistaken, the hf is the enthalpy of the fluid when it is exactly at a saturated liquid state (meaning the fluid is 100% liquid, 0% gas). At state 4, it is not the same enthalpy because the fluid at state 4 is not at a saturated liquid state. It is a mixture of vapor and gas (state 4 is inside the liquid-vapor dome). So you need to find liquid-vapor ratio of state 4 by finding the quality (x=0.873 meaning the fluid at state 4 is 87.3% gas). Then you can estimate the enthalpy between the hf (h at saturated liquid state) and hg (h at superheated vapor state) using the enthalpy-quality formula.
I’m cooked
Keep cooking! Remember to always take breaks. You got this!
how do i solve last question at end of video?
Here it is: www.directhub.net/wp-content/uploads/2022/08/ideal-gas-mixture-2-solution-1661186754.1069.png
what if the beam is frame
Question: FE handbook: Latest Edition Pg#263... Effective Horizontal force Formula PA2 = σ1' KAH2 +1/2 (σ2' - σ1') KAH2 In 1st part of formula given(σ1' KAH2) which KA value we use if unit weight are different for dry and saturated conditions (dry and saturated).
why is this ideal plug flow? assumed CMFR (in current handbook) with "continuous plug flow reactor" in the problem statement
g? Did I miss something?
@@ole2445 Didn’t say this in video, but “gamma” = unit weight of water = 9810 already accounts for the gravity value.
The second half is completely wrong. just ignore
Show me your work . Or explain
I wonder why you did not consider reaction forces at point A
The “free bodies” in this case are the beams. Therefore we would strictly focus on drawing the free body diagrams for the beams while neglecting the reactions at A since they do not impact either beam.
Bro act like as if he is talking in sign language
Easy.....lol
Is 19.97 kW correct for the Power question?
Please excuse my arithmetic mistake. The correct written solution is shown below: www.directhub.net/wp-content/uploads/2024/09/image-2.png
The animation is very good
Thank you!
The FE really isn’t that difficult. Shouldn’t take more than 6-10 weeks of study time
For Impulse Momentum priniciple,it is the change in force or the net force in the system is equal to change in momentum right. why did you use F as the resultant force. The resultant force should be zero right since it is acting equal and opposite direction.
Correction: For any softening problem we will use the EQUIVALENT RATIOS. Using this ensures the amount of lime (or soda ash) added will exactly match the amount required to neutralize or precipitate the hardness ions, based on their charge equivalency. The Stoichiometric Ratio isn't accurate enough since it's based only on the balanced chemical equation which tells us the ratio of moles of reactants required to completely react with each other. A better method is to use the equivalent ratio which accounts for both the charge and the amount of substance. It is used because water softening processes typically involve ionic reactions where the focus is on balancing the positive and negative charges rather than just the moles of reactants. The corrected proportion equation should be: 2 equivalent of Lime/1 mol Mg(HCO3)2 = X / 50 mg/L The equivalent ratio for the reaction is equal to the molar ratio. This won't always be the case but it is so for these chemical softening equations.
