Calculating Air Temp Increase from Atmospheric to 3 Bar Pressure

[Sakthi1267]

How to calculate the raise in temperature of air when it's pressurized by a piston type air pump from atmospheric pressure to 3 bar(gauge pressure) ?

 

[Sunfire]

one can read wikipedia on "Adiabatic process", there are expressions involving both pressures, temperatures and gamma = 1.4 for air

 

[Aneesh]

it depends upon the process.whether its isentropic or polytropic.If its isentropic then the formula wouls be

T2\T1=(p2/p1)^(gamma-1\gamaa0.gamma=1.4

 

[Aneesh]

sorry its gamma -1\gamma.t1 may be normal temp
