Creating a New Model to Predict Cooling Tower

2021-4-21  The current cooling tower model used in CWSAT was developed by Benton [2]. A careful investigation of the current model indicates that the prediction capability of the model at lower wet bulb temperatures (close to 40°F and below) and at low fan power is not very accurate. This could be a result of the lack of data at these
