What is the average amount of water volume that evaporates from a cooling tower?

The average amount of water volume that evaporates from a cooling tower is approximately 5%. This percentage reflects the typical rate of evaporation based on the operational conditions and design of cooling towers in power engineering applications.

Cooling towers are designed to remove excess heat from water used in industrial processes or power plants. During this heat exchange process, a portion of the water evaporates into the atmosphere, which is essential for maintaining the efficiency of the cooling cycle. The evaporation rate can vary depending on several factors such as the temperature of the water, the ambient temperature, humidity levels, and the specific design of the cooling tower.

A 5% evaporation rate is a widely accepted average, striking a balance between effective cooling and water conservation. Higher or lower rates would depend on specific environmental and operational factors, but 5% is a good general benchmark used in the industry for calculations related to water usage, makeup water requirements, and thermal performance assessments of cooling systems.
