Air enters a pipe at 25 0C, 100 kPa at a flow rate of 36 m3/hr. A heater on the outside of the pipe draws 8 amps at a voltage of 120 V. All the heat from the heater is transferred to the air (well insulated and wall t is small). Assuming that the air behaves as an ideal gas and ignoring KE and PE, (a) determine the mass flow rate of the air in kg/s and (b) the temperature of the air at the exit.
