1kg of air at 1.02bar, 20°c is compressed reversibly according to a law pv¹°³=constant, to a pressure of 5.5 bar, calculate the work done on the air and the heat supplied the compression.​

Fluids at rest possess no flow energy. a)- true b)- false

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
