A building is designed for the following cooling loads. Room specific heat gain and latent heat gains are 310 kW and 100 kW respectively. The room is maintained at a dry bulb temperature of 25°C and relative humidity of 50%. The outdoor air is at 28°C with 50% relative humidity, 10% by mass of outdoor air is supplied to the building. If the air supplied to the room should be at a temperature lower than 18°C, detemine the following. (a)...

Moist air at 20°C, 1 atm, and 43% relative humidity and a volumetric flow rate of 900 m/hrs. enters a control volume at steady state and flow along a surface maintained at 65° C, through which heat transfer occurs. Liquid water at 20° C is injected at a rate of 5 kg/hr and evaporates into flowing stream. For the control volume, Wev =0, and kinetic and potential energy effects are negligible. Moist air exits at 32°C, 1 atm. (a) draw...
