This study aims to develop a mathematical model for the prediction of heat and mass transfer coefficient as a function of parameters such as temperature, water and air flowrates using the existing counter-current wetted-wall cooling tower. Three sets of experimentation are performed for three different variations of the given parameters. An analytical calculation of heat transfer coefficient and mass transfer coefficients assuming linear temperature profiles and considering straight equilibrium line following a log mean difference enthalpy driving force respectively is done.Multiple Linear Regression is the method used to used to arrive at the model. It is done by getting the linear correlation between the heat and mass transfer coefficients and the temperature, the air and water flowrates respectively. To arrive at this situation, two parameters are held constant while varying the other. Such as varying the inlet temperature while taking the flowrates constant. In this condition, the heat and mass transfer coefficients are evaluated as a function of temperature. The same goes with the evaluation of heat and mass transfer coefficients as a function of air and water flowrates.
