03:Moist air at28°C dry-bulb, 20°C wet-bulb and 101.325 kPa barometric pressure and mass flow rate of 0.25 kg/s, flows over a cooler coil and leave it at a state of 10°C dry-bulb and 7.046 g per kg of dry air, the air is reheated to 15.5°C and supplied to the room. calculate the mass of dry air which must be supplied to the room in order to maintain a dry-bulb temperature of 21°C and 50% RH. Heater surface temperature is 150°C. Find the exergy efficiency of the heater. Discuss the reason of low heater exergy efficiency. 2. Room heater Cooling coil
