Air is used to heat a room. The flow rate of the entering air to the heating unit is(2.50 m3 /s) at 17°C and 100 kPa. The entering air passes through a heating unit that uses (15 kJ/s) for the electric coils. If the heat loss from the heating unit is 200 W, what is the temperature of the exit air? Assume Cp air =1 kJ/Kg. °C
