Unformatted text preview: 3 at the exit, determine the percent increase in the velocity of the air as it flows through the dryer. #4 (5-18, 6 th edition; 5-15, 5 th edition) Refrigerant 134a enters a 28 cm diameter pipe steadily at 200 kPa and 20 C with a velocity of 5 m/s. The refrigerant gains heat as it flows and leaves the pipe at 180 k Pa and 40 C. Determine (a) the volume flow rate of the refrigerant at the inlet, (b) the mass flow rate of the refrigerant, and (c) the velocity and volume flow rate at the exit. #5 (5-31, 6 th edition; 5-30, 5 th edition) Air enters an adiabatic nozzle steadily at 300 kPa, 200 C and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm 2 . Determine (a) the mass flow rate through the nozzle, (b) the exit temperature of the air, and (c) the exit area of the nozzle....
