After leaving the condenser of a power station, water enters the top of a cooling tower as a spray and falls over baffles to the bottom where it is recirculated to the power plant. at the time air enters the bottom of the tower, is sucked up by a fan, and billows out of the top generating huge white clouds. the water enters the tower at 35℃ and 120 ݇݃kg/s and is cooled to 25℃ by the air that enters at 20℃, 50 % relative humidity, and atmospheric pressure. if the air leaves saturated at 30℃, calculate the required flow rate of air.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
