Air Compressibility Factor

I need to calculate the volume of screw compressor in Nm3/h , so based on gas low i have :

V2=V1*(P1/P2)*(T2/T1)*(Z2/Z1) 

where V in [m3/h]; P in [ atm abs ] ; T in [K] , and i need V2 in [Nm3/h]

the problem is that i need to calculate the compressibility factor Z  to get V2. i didn't find any helpful document for my case .

Hi ,

Did you consider your favorite search engiine ?

an example:

you may also use the excel sheet attached .

anyway it should be very close to 1.

Good luck
