Air Temp & Pressure: Charts, Data Books & More

[RKD89]

Hi guys
Can anyone tell me if there are charts available to relate temperatures and pressures of Air ( similar to steam tables )
Or do the ideal gas equations ( PV=nRT) hold true in practice as well

The most I could find is Compressibilty Factor on Wiki n Wan Der Waal's Equations


PS: Heard there are something known as Data Books

When air is Used as refrigerant , are there charts available to relate pressure n temp??
or I just Use d Gas Laws??

The perfect gas law with compressibility factor determined from Wan Der Waal's Equations is how I always do it.

In industry we typically use computer databases for fluid properties. Those databases generally interface with most engineering software. Our company has their own proprietary one as I'm sure many companies do. The one most widely used by companies that don't have their own is NIST REFPROP. You can purchase it online here:
