Air at 1.02 bar, 22°C, initially occupying a cylinder volume of 0.015 m 3 , is compressed reversibly and adiabatically by a piston to a pressure of 6.8 bar. Calculate :
(i) The final temperature
(ii) The final volume
(iii) The work done on the mass of air in the cylinder.
1 kg of air at 1.02 bar, 20°C is compressed reversibly according to a law pv 1.3 = constant, to a pressure of 5.5 bar. Calculate the work done on the air and heat flow to or from the cylinder walls during the compression.
