Which variable affects the efficiency of a cooling tower significantly?

• A. Humidity
• B. Wind speed
• C. Water temperature
• D. Source of electricity

Answer: (C)

The efficiency of a cooling tower is significantly affected by water temperature. In cooling tower operations, the primary function is to dissipate heat from processes or systems using water. When the water enters the cooling tower at a higher temperature, it allows for a greater capacity to absorb heat from the air within the cooling tower. The cooling process relies on the interaction between the warm water and the cooler ambient air, promoting evaporation, which ultimately lowers the water temperature. As water temperature decreases effectively through this exchange, the overall efficiency of the cooling tower improves. If the water temperature is too high when entering the cooling tower, it reduces the potential for effective heat transfer, leading to decreased performance. Therefore, maintaining optimal water temperatures is crucial for maximizing the cooling tower's efficiency. Other factors like humidity and wind speed do play a role, but they do not have as direct a correlation to the overall efficiency of the cooling process as water temperature does. The source of electricity primarily impacts operational aspects rather than thermal efficiency.
