Analyzing Cooling Towers

Liquid water at 100°F enters a cooling tower operating at steady state, and cooled water exits the tower at 80°F. Data for the various streams entering and exiting the tower are shown in Fig. P12.104. No makeup water is provided. Determine(a) the mass flow rate of the entering atmospheric air, in lb/h.

(b) the rate at which water evaporates, in lb/h.

(c) the mass flow rate of the exiting liquid stream, in lb/h.
