EXCELLENT VIDEO , LOAD CALCULATION DUCTING & PIPING EXCEL SHEET REQUIRED
Dear ,
Really appreciated.
The way ypu explained is superb.
Thank you
@@hvacsimplified
Could you also upload ESP calculation and sheets related to it
Very useful videos you are uploaded...thnx Sir
Thank you Jeet
Good Explanation
Nice work
Great job
Can u please send me this excel sheet
Like 1.6k Have a good day to u my friend. Thanks for sharing this wonderful video
Welcome
Appreciate your work this will helpful to many people. I have 3 questions
1.Please make us understand the range of primary pump and secondary pump the consideration range for the head.
2.please explain about cooling tower pump head calculation.
3.please explain how should we consider horizontal and secondary pump head should we consider it to be same. Fyi
Thanks sir..very informative vedioes..kindly make more vedioes on HVAC...TESTING AND COMMISSIONING.
its beneficial for me thanks sir
really usefull
Thank u sooo muchhh
Very nice video sir ...thanx
Welcome Faizan
Excellent
Thanks for this education
Pleasure, always knowing it is helpful
So nice
MD ARMAN SB can u give me ur contact no.
So nice ,please tell me why we have installed motorized or 2 way valve in return line.
Hi. Could you share the exel sheet and the table from where you took the Loss values in feet? thanks
Alhamduilliha it is a very useful and important topic i get revised with this video thanks a lot.May Allah swt bless u for helping us thanks once again.
Please share the excel sheet in the description or in thr reply of this comment
very nice video. one question only to calculate head pump when we calculate to user, do we do x2 for the return piping? or only to the unit?
explained very well!!can u plz do a video about chilled water flushing process,make up water,draining etc??
thank you ... great ved
Q . is there any friction loss difference in Horizontal and vertical pipe ?
thanks for vedios .
sir chilled water pipe sizing me friction loss kaise find out karte h?
Thank bro
I have one question- to calculate head in vertical pipe we have fo use same method or simply we have to take vertical lenght+friction loss
very good video, nicely explained. Great man. God bless you . share more videos on design of stair case pressurization system & Smoke extract design . Car park ventilation video
sure will do it.
Please explain Sir; how do you do head calculation for the multi-pump's chillers system, here in your this lecturer not clear, head loss and GPM can be divided to select pumps to match demand flow?
Please tell me
I have an issue regarding reciprocation compressor failure of Air cooled chiller(240 ton). frequently valve reed are breaking. what its reason and solution
Hi Sir,
Do You have English Version for this one?
Sir please add excel sheet in the description
Weldone sir.
Thanks Anujm.
HVAC Simplified Online Training - By AMK sir can you provide excel sheet
Amitjhasky@gmail.com
Sir,if the pipe is in vertical position then head = total length of pipe,but what is the pipe head for horizontal laying pipe?
In the chilled Water Pipe system the system is a closed loop therefore there is no difference if the Pipe is vertical or Horizontal.
love you
Thanks
hI....How evalute the energy flow at Primary Circuit (inposted by the primary pumps) for consider it on the desing HEAD at the secadary circuiT???
Thank you for making such an informative video.
Sir, the longest length is considered for calculation of the pump head, but there will be head loss through AHU's coil which are connected before the last AHU. Why we aren't considering the head loss of AHUs?
stunning and amazing sir,kindly share excel sheet for practice and learning
Excellent sir
Can u please explain the tee branch and tee run how to take this values.
Thanks for your explanation for Pump Head Calculation. please sir can we get this excel sheet?
Good brief description but 2 things need clarification
1. U didn't mentioned about how to take pressure loss of valves..it is not same like fittings, u have to know kv value of valves first
2. For F&R pipes did u taken the length of F&R both pipes
Hi , Thanks for the video , please share the pipe fittings pressure loss chart and source of it. thanks
nice video sir ji,... please clear my doubt pump head calculation is different head ht =hs+hd+(pressure receiving-- pressure reservoir) when we use this formulae ?or head loss calculation is diiferent right ? pump head loss helps to determined what capacity of motor (hp) required for pump.
From where did you get 2.3 ft/ 100ft head
Dear Sir,
Kindly upload your pump head calculation sheet by which we can download.
Please share the link of carrier pipe fittings data,
Thanks
So the Primary pump should overcome pressure losses of the chiller loop only: from the suction point, through the chillers, to the suction point of the secondary pump. So it will have always less Head than the secondary pump that should handle the pressure losses throughout the supply and return of all the distribution loop ??
bhai, mere ek doubt hai HP jo nikal rehe hain wo ek pump hai , in case 3 pumps hai primary side mai tho apan jab calculate kar rahain hai wo ek pump hai na bhai , ab wo head loss jo aya hai usko apan HP ke formulea mai use karne baad jo HP arahai wo single pump hai na bhai.
Do you have Method for Chill water cleaning and flush line? Can I have this method.
dear sir i have a doubt that,at the condition when both primary and secondary pumps are involved, some of the other tutorials, for primary pumps people are taking whole pipes from the units to the chiller and for secondary pumps all the pipes from the chiller to units..is that method is feasible? and do we need to take the static height also?
The terminalogy Primary means the pipes related to Chiller's only.
Secondary can be in various type, such as from the chiller to the building or from the chiller to the building secondary and saperate for the building as tertiary
@@hvacsimplified thanks for your reply.. if the chiller pumps at the ground floor, and chiller at higher level,do we need to consider the static height also?..If possible can you send me the excel sheets to my email babugd@gmail.com
In a Closed System, I believe only Supply to the Last (Critical) Unit needs to be considered, not the Return Piping. Because If you can Supply to the Unit, the Return will automatically come to the Pump. IS it Correct? But I must say, your video quality is very good with good understanding of the subject.
Hi, by any chance u have the answer for this?
I have watched this video a couple times to try understand it properly, i do have one question though, when selecting the Head Loss to dimension the pump, knowing how many l/s or GPM, you account for pressure loss in the piping and fittings to the furthest point of your piping, yes? and not all of them combined, imagine theres a valve in bedroom with FCU 4, and it has a drop pressure of 0.3 and the equipment drop pressure also 0.3, you add them in your equation to head calculation but only one of them, and not all FCU combined, right? Sorry if its a dumb question :p
Yes. When calculating the Pump Head the farthest length along with it fitting to be calculated one more thing the designer/Engineer need to see the critical path also.
Because sometime instead of the longest length there might be another route which might be shorter in length but have more fittings of pressure drop.
@@hvacsimplified Thanks a lot for your explanation and tip in such short notice, it does make sense, any chance your available to help me dimension a system? it is a circuit with primary and secondary pumps and inertia tank, the pumps with your video for pressure drops and head loss, also the pipe selection that is all ok, but for inertia tank & buffer, i have no idea what are the dimension criteria, if the tank is pressurized etc, i would be very gratefull, thanks
sir where we can get the chart
Sir while considering head, Is it necessary to consider to which height pump have to pump water in case of closed loop, as in your AutoCAD drawing pipe got risers ?
I understood pipe fitting loss and loss per square feet, what about height difference sir?
And from where to get losses due stariner, drv and all?
Thank you
The head is to be considered till the last FCU or AHU. now you need to first understand the type of pumping such as Primary and Secondary Pumps.
how to get this excel sheet. please advise...
Sir, at 8:24, how we want to estimate the GPM?
Sir plz make a video on AHU manifold drawing...
Can you please make a video on chiller valve Mock up.
Good Shai friend
Sir pump nameplate me jo discharge &head actual meaning kya hota hai
Is same pressure drops for horizondal straight pipe and vertical straight pipe
In the closed loop system. Yes
Sir..Plzz tell me about marine HVAC system.
Sir please explain Expansion tank sizing calculation
Hi sir. Great work.
I have confusion . I agree with you for division of flow sir but head will not be divided in case of more than one pump acting as schwps
Hi Azam, Primary and Secondary Pumps are two different. Can you explain in detail about where we did not understood. So we can understand each other. 😊
Am on job but will inform you sir the exact time of video.
Please explain condensor pump calculation
Excellent video sir .Thank u so much sir pls send me this excel sheet .which is help to me learn deeply this topic.👍
pls provide me the arrier pipe fitting pressure loss table
If we are connecting secondary pump in parallel connection, then its pump head has to be same. You cant divide the total head with number of pumps.
sir can we get this excel sheet ?
asslam alikum sir DRV ka 120' kaise ayya please valve losses ka table send kariyea
thanks
