Pls. Answer thank you! The evaporative condenser of an ammonia refrigeration plant has a water flow rate of 100 kg/s and enters a natural draft cooling tower at 43 °C. The water is cooled to 30 °C by air entering at 27 oC db 24 °C wet bulb. The air leaves the tower as 90% RH and 32 °C db. Calculate the percent of make-up water needed the tower. At 27 °C db and 24 °C wb: h = 72.5 KJ/kg, w = 0.0178 At 90% RH and 32 °C db: h = 102 KJ/kg, w = 0.0275
