The air used to heat an auditorium flows into the heating unit at a rate of 145 m3/min at -3°C and 100 kPa. Heating coils in the unit deliver 80.0 kW of heat to the air. The heat loss from the unit is 300 W. The specific enthalpy change of the air can be calculated as Hˆ=CpT, where Cp is the heat capacity of the air. Assume a value of Cp = 1.00 kJ/(kg °C). What is the temperature of the air exiting from the heating unit?
