Air at 300 K and 100 kPa steadily flows into a hair dryer having electrical work input of 1500 W. Because of the size of the air intake, the inlet velocity of the air is negligible. The air temperature and velocity at the hair dryer exit are 80°C and 21 m/s, respectively. The flow process is both constant pressure and adiabatic. Assume air has constant specific heats evaluated at 300 K.

(a) Determine the air mass flow rate into the hair dryer, in kg/s.

(b) Determine the air volume flow rate at the hair dryer exit, in m3 /s.
