Couldn't you just read the reduced pressure from the intersection of the Tc and Vc lines? I get Pr=~0.35. When multiplied by the critical pressure (72.9 atm) I get 25.515 atm, which is pretty close to the value you calculated, and likely within the error of the plot.
i keep getting a really high number as my Vr please help me with this question,"Duduced the pressure exerted by 75kg of CO2 gas kept within a canister of capacity 2500L for a temperature of -30c Tc=304.2K, Pc=72.9atm. Mr=44gmol^-1" when i calculate Vr i keep getting a number over 5, please help :/
Thermodynamics features several dimensionless parameters for convenience that may not make sense on the surface (for example, relative pressure and temperature also are dimensionless parameters used in problems involving entropy calculations). Reduced pressure and temperature are additionally convenient in presenting compressibility expressions derived from equations of state.

I am thankful. This video helped me a lot. From KSA
Thank you so much! I have my final tomorrow and this definitely helped a lot! :D
...you have a final tomorrow and now only you're learning the basics?? what a noob. mine is in two hours XD
@@theintern7054 huh ?, i'm watching this while writing mine
well explained than my lecturer, thanks!!!
extremely helpful. gonna ace my test today
This was so well structured and explained! My thanks 😊
you are the best man!! I couldn't thank you enough. you just made my life a whole lot easier!!!
This was a very helpful review of reading these charts. Thanks.
That was explained so well, thanks
Thanks for helping me understand how to use the compressibility chart.
If I could use one mega like once in my life, I would use it on this video.
Thanks a lot mate, this is brilliant.
hey
please can you give me the link. that contains all the videos related to chapter.5 and 6 because there are many videos here 😢
Can anyone point me to an easy-to-understand (or well explained) correlation for the Z-Factor that is simultaneously quite accurate?
Thanx, you really helped me :)
wow 5 star, easy to follow
Hi there, how to find z when T is not given?
The compressibility chart contains information for pr, vr, and Tr. If two of the variables are known, the other can be found.
Couldn't you just read the reduced pressure from the intersection of the Tc and Vc lines? I get Pr=~0.35. When multiplied by the critical pressure (72.9 atm) I get 25.515 atm, which is pretty close to the value you calculated, and likely within the error of the plot.
really helpful for me thankssss. a. lottt
thank you !
I find p to be 28.72, if it is rounded to 2 digits, shouldn't it be 29 ?
The difference is in rounding throughout the calculations versus carrying the digits throughout.
thank you
Thanks! :)

Check your units.
🥺🥺😞ما افتهمت شي
why do we create reduced temp and pressure"? it has no justification. makes no sense.
Because the compressibility charts available are in terms of reduced temperature and pressure
Thermodynamics features several dimensionless parameters for convenience that may not make sense on the surface (for example, relative pressure and temperature also are dimensionless parameters used in problems involving entropy calculations).

@@small_ed thank you for answering. much apreciated.
noice
Badly explained
Thank you
