Exercise 5.11 A water flow of 1 kg/s leaves the condenser of a chiller at 45 C and enters a cooling tower. An airflow of 1500L/s at 30C db and 20 C wb enters the tower. Assuming that one of the two flows reaches thermal equilibrium, determine the temperature of the water leaving the cooling tower, the tower capacity (kW), and water loss. Also compare between actual and simplified (mass of air and water assumed constant) system analysis Hint Compare between 2 equilibrium states: Equilibrium state 1 (Tair Twater in) and Equilibrium state 2 - (Twater = For each equilibrium state: out = =Twb) Determine the air inlet enthalpy, specific volume and air mass flow rate. Determine the water inlet enthalpy Solve water mass balance Solve energy balance to get T 43
