: A Room Is Maintained At A State Of 20 C Db And 50 Rh By Supplying Cool Air At A Rate Of 0 9 Kg S The Total Cooling Lo 3 (28.01 KiB) Viewed 65 times

A room is maintained at a state of 20 °C DB and 50% RH by supplying cool air at a rate of 0.9 kg/s. The total cooling load of the room is 9 kW. The moisture contents of the cool and room air are 0.0066 kg/kg and 0.0074 kg/kg respectively. By taking the latent heat of vaporization of water at 0°C as 2,501 kJ/kg, determine: (a) latent heat gain of the room; (b) sensible heat gain of the room; and (c) sensible heat ratio of the room.
