potential energy effects

12.107  Liquid water enters a cooling tower operating at steady state at 408C with a mass flow rate of 105 kg/h. Cooled water at 258C exits the cooling tower at the same mass flow rate.

 

 

Makeup water is supplied at 238C. Atmospheric air enters the tower at 308C, 1 bar, 35% relative humidity. A saturated moist air stream exits at 348C, 1 bar. Determine

(a)   the mass flow rates of the dry air and makeup water, each in kg/h.

(b)  the rate of exergy destruction within the cooling tower, in kW, for T0 5 238C.

Ignore kinetic and potential energy effects.
