A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water’s temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower. Cooling tower acts as the cooling […]

PSYCHROMETRY is the science of studying the thermodynamic properties of moist air and the use of these properties to analyze conditions and processes involving moist air. Moist air is a mixture of dry air and water vapour. In atmospheric air, water vapour content varies from 0 to 3% by mass. Is often used in the
