Cooling towers are large evaporative cooling systems that can be used to transfer heat from warm water to the atmosphere by evaporation of the water to be cooled.
Prepare a preliminary design for a cooling tower that will cool 30,000 kg/s of water from 40.0°C to 30.0°C. Atmospheric air enters at 20 ± 10°C with a relative humidity of 45 ± 15%.
Establish the overall physical dimensions of the cooling tower, air flow rate, water pumping power, fan power (if forced convection is used), makeup water requirements, air exit conditions, and so forth (Figure below).
