A plant has a cooling tower for their closed-loop cooling water system. On a warm summer day, the ambient temperature is 90 F. You measure the wet bulb temperature and it is 67 F. The hot cooling water fed to the cooling water tower is 115 F. The evaporation rate in the cooling tower is 2000 pph. The cooling tower is designed to have an approach temperature of 5 F. The cooling tower has a source of make-up water that has 100 ppm (weight fraction = 0.0001) of dissolved solids in it Vent (V) Makeup (M) Cooling Water (C) 1) What is the dew point of the air? 2) What is the Relative Humidity of the air? 3) What is the Wet Bulb Temperature? 4) What should the outlet temperature be if the tower is operating at design approach temperature? 5) What should the cooling tower range be if the tower is operating at design approach temperature? 6) How is heat removed from the cooling water? 7) What would happen to the concentration of dissolved solids in the water if there was no blowdown flow? 8) From question #7, how would this impact the piping and equipment in the system? 9) How much blowdown flow is required to maintain the dissolved solids at 300 ppm (weight fraction = 0.0003)?
