## What is Cooling Tower ? Describe With Schematic Diagrams

Maināguri Cooling tower is a device which is used to extract waste heat by the stream of water of low temperature. The cooling system of the cooling tower is known as the evaporative cooling system. In this process small amount of heat is rejected by evaporation and the most of the heat is rejected by the stream of water.  Most of the times water [...]
