A horizontal "cold air blower" consists of a fan, a cooling coil and an exit nozzle as shown. Figure 2: Blower schematic. The power of the fan is 60 W and the power to the cooling coil is 0.46 kW. During its passage through the blower, the air experiences a heat gain of 44 W. A steady flow of air enters the fan with a negligible velocity at a pressure of 1028 mbar, a temperature of 12 C and a volumetric flow ate of 0.37 m/min. The air exits with a velocity of 25.5 m/s and a pressure of 1195 mbar. Treating the complete arrangement as a steady flow system, determine the exit temperature of the air. The temperature of the air exiting the system, in C, correct to three significant figures is: A horizontal "cold air blower" consists of a fan, a cooling coil and an exit nozzle as shown.
