Calculate the velocity at the exit of a diffuser when air at 100kPa and 20 degree C enters it with a velocity of 500m/s and exit state is 200kPa and 90 degree C. R-134a at 800kPa and 100 degree C enters an adiabatic nozzle steadily with a velocity of 20m/s and leaves as sat-V at 400kPa. Determine 1) temperature at the outlet; 2) the velocity at the outles; 2) ratio of the inlet to outlet area (A1/A2)
