Evan Draplin hey there man! thank you, i really appreciate you take the time to make such comments =) I do it because there is not enough material out there! Keep checking out the material and please share with your friends so we can grow up as a community! PS: check out my webpage, you may find it user-friendlier thank youtube!
Chemical Engineering Guy I think more people would find these videos if you wrote in your description the book you are referencing, it took me a long time to find your videos. But I'm pretty sure you are following the same text book my course uses. But I will definitely spread the word, thanks again!
Evan Draplin yep, ill keep in mind to add the book its based on the book of Richard Felder: Elementary Principles of Chemical Processes 3rd Edition Good luck studying!
Hi, Nice explanation. Wanted to know if chart for compressibility is not available or need to calculate Z from equation then what is formula for calculating Z from Pr and Tr.
Hi Sir, first of all thank you so much for your videos, you have helped me a lot. I have a question, if the problem stated: Fifty cubic meters of CH4 flows through a pipeline at 40 bar manometric pressure, then you first convert that to absolute pressure right? I ask this because many textbooks dont specify which pressure you have to use (absolute or manometric) when calculating the compressibility factor.
What happens when you have a very low reduced pressure? For example, I'm working with saturated steam at T= 100 degrees F, and I determined that pr= 0.00029, we just assume that this is in ideal state?
+Litcy Barreto since pressure is too low, you may assume ideal gas, the molecules are so apart, that you may assume they won't interact between each other
Very helpful my friend, thanks a lot. You helped me to skip reading 50pages of a big chemical Eng book
Thats nice, 50 pages is not that easy to read/digest/understand
I was always told if you appreciate something somebody does.. let them know. Thanks again man!
+Moogy Jones Thank you! hope you are enjoying the course
Thank you for these videos, I couldn't find anything else like this on the internet. Really helpful for my materials balance class

awesome!
You just saved my life. Thanks Bro
Hi, Nice explanation. Wanted to know if chart for compressibility is not available or need to calculate Z from equation then what is formula for calculating Z from Pr and Tr.
I'm pretty sure you can find experimental correlations, but the rule of thumb is to have the diagram
very helpful videos, it cant be better than this
thanks bro! I really appreciate this comments!

You must always use total pressure ( absolute pressure) if not stated, assume it is absolute. if it states psig, this is gauge pressure!
The generalised compressibility char you've used stops at Tr =3.5. i happened to get a Tr = 5.61. How to I go about this?
You will need a larger one! You can find those on the internet, simply use Z Chart, expanded
I found this really helpful! Out of curiosity, what is the song you used in the introduction?
Nice! Im glad! The music is free royalty music, can't remember the title...

for the last slide rite..? y the formula doesnt have " n " ...in (pv=zrt) is it because they didnt give so we can ignore...?
the "n" is in the "v" value, which is v = V/n, specific molar volume
is that you in dp?
Very helpful
playbwooi96 thanks man! I really appreciate these comments!
and yeah one more, wen they say find the specific volume...do they mean this V^ or V, where this V ....we find by multiplying (V^ wit n )
yes, specific volume is v = V/n, or simply total volume of gas over total moles of gas... we use either "v" or "V^" to denote it
thanks.
Im glad it helped!
Salute you sir
Hi there!
BUT SIR YOUR VOICE IS VERY LOW
