Wet air out Water in Air in Air in Water out An cooling tower (see the figure above) is used to cool water from 110 to 80°F. Water enters the tower at a rate of 117639 kg/h. Dry air (no water vapor) flows into the tower at a rate of 66674 kg/h. If the rate of wet airflow out of the tower is 74424 kg/h, determine the rate of cooled water flow in kg/h.
