THANK YOU In the diagram below inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process. Evaporation on the pool resultsin saturated air at the exit. The pool of liquid water is assumed to be at the same temperature as the exitair. Discharge fans at the exit provide a volumetric flow rate of 800,000 ft3/min. Problem #2: Assume that the R134a chiller is turned off such that Qout = 0, but the evaporative coolersystem continues to operate. Determine:a) The exit temperature, T2 (°F)b) The mass flow rate dry air through the system (lbm/sec).c) The rate of liquid water resupply required for continuous operation (lbm/hour).arrow_forward
