Liquid water at 50°C enters a forced draft cooling tower operating at steady state. Cooled water exits the tower with a mass flow rate of 80 kg/min. No makeup water is provided. A fan located within the tower draws in atmospheric air at 17°C, 0.098 Pa, 60% relative humidity with a volumetric flow rate of 110 m3/min. Saturated air exits the tower at 30°C, 0.098 MPa. The power input to the fan is 8 kW. Ignoring kinetic and potential energy effects, determine

(a) the mass flow rate of the liquid stream entering, in kg/min.

(b) the temperature of the cooled liquid stream exiting, in °C.
