Thermofluids The Gas Laws

The combination Gas law of pV/T = C can be used to solve most problems because it combines Boyle`s, Charles` and the pressure law. It`s normally used in the form p1V1/T1=p2V2/T2.

A variation is one where the Characteristic Gas Constant `R` is used. For example, R for AIR is 0.287 kJ/kg K.

Question: What are the units for each component of the pV=mRT equation?

The combined Gas Law allows us to do all calculations.

(p1V1)/ T1 = (p2V2)/T2

and pV =mRT where R is the characteristic gas constant.

For AIR, R= 0.287 kJ/kg K

Question: What are the units for all the components of the pV = mRT equation?
Also, prove the units for R = kJ/kg K.
