Cooling Tower

Cooling towers are used throughout industry to remove heat from the processes. Typically, a cooling fluid (water) is pumped from the cooling tower into the plant and through heat exchangers to remove heat from unit operations such as condensing steam, cooling a reactor, cooling for a refrigeration unit, etc. The students cool a recirculated water stream with a heat load simulating the processes being cooled.  Various characteristics are changed during the experiment such as air flow rate, water flow rate, air temperature, etc.  The students collect the data and develop mass and energy balances around the cooling tower.
