Question

A pressure vessel that has a volume of 10 m3
is used to store high-pressure air for
operating a supersonic wind tunnel. If the air pressure and temperature inside the vessel
are 20 atm and 300 , respectively. What is the mass of air store in the vessel? Calculate
the isothermal compressibility for air at a pressure of 0.5 atm. Calculate the isentropic
compressibility for air at 0.5 atm and compare the result.
