Mass Flow Rate Problem
Water exiting the condenser of a power plant at 38ºC enters a cooling tower with a massflow rate of 4.5 x 107 kg/h. A stream of cooled water is returned to the condenser from acooling tower with a temperature of 30ºC and the same flow rate. Makeup water is addedin a separate stream at 20ºC. Atmospheric air enters the cooling tower at 25ºC and 35%relative humidity. Moist air exits the tower at 30ºC and 95% relative humidity.Determine the mass flow...

(10 pts) Six-thousand cubic feet per minutes (C.F.M.) of atmospheric air at 28°C (dry bulb) having a wet bulb temperature of 23°C is to be cooled in an air conditioning system. The air conditioning system lowers the dry bulb temperature of the air to 20° C. Cooling with dehumidification is accomplished using chilled water loop. The chilled water enters the loop at 5°C at a rate of 280 kg/min and experience a 5°C temperature increase. The atmospheric pressure is 1...

a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...

Water entering a wet cooling tower at 35°C at a rate of 100 kg/s
is cooled to 22°C in the cooling tower by air that enters the tower
at 1 atm, 20°C, and 60% relative humidity and leaves saturated at
30°C. The makeup water of 22°C is supplied to the outlet to make
the mass flow rate of the cool water the same as that at the inlet,
see Figure Q5.
