1 Chapter 14, Problem 27. A house contains air at 25 C and 65 percent relative humidity. Will any moisture condense on the inner surfaces of the windows when the temperature of the window drops to 10 C?
2 Chapter 14, Problem 28. After a long walk in the 8 C outdoors, a person wearing glasses enters a room at 25 C and 40 percent relative humidity. Determine whether the glasses will become fogged.
3 Chapter 14, Problem 34E. The air in a room has a dry-bulb temperature of 80 F and a wet-bulb temperature of 65 F. Assuming a pressure of 14.7 psia, determine (a) the specific humidity, (b) the relative humidity, and (c) the dew-point temperature.
4 Chapter 14, Problem 42. A room contains air at 1 atm, 26 C, and 70 percent relative humidity. Using the psychrometric chart, determine (a) the specific humidity, (b) the enthalpy (in kj/kg dry air), (c) the wet-bulb temperature, (d) the dew-point temperature, and (e) the specific volume of the air (in m 3 /kg dry air).
5 Chapter 14, Problem 68. Air enters a heating section at 95 kpa, 12 C, and 30 percent relative humidity at a rate of 6 m 3 /min, and it leaves at 25 C. Determine (a) the rate of heat transfer in the heating section and (b) the relative humidity of the air at the exit.
6 Chapter 14, Problem 69E. A heating section consists of a 15-in.-diameter duct that houses a 4-kW electric resistance heater. Air enters the heating section at 14.7 psia, 50 F, and 40 percent relative humidity at a velocity of 25 ft/s. Determine (a) the exit temperature, (b) the exit relative humidity of the air, and (c) the exit velocity.
7 Chapter 14, Problem 79. An air-conditioning system is to take in air at 1 atm, 34 C, and 70 percent relative humidity and deliver it at 22 C and 50 percent relative humidity. The air flows first over the cooling coils, where it is cooled and dehumidified, and then over the resistance heating wires, where it is heated to the desired temperature. Assuming that the condensate is removed from the cooling section at 10 C, determine (a) the temperature of air before it enters the heating section, (b) the amount of heat removed in the cooling section, and (c) the amount of heat transferred in the heating section, both in kj/kg dry air.
8 Chapter 14, Problem 80. Air enters a 30-cm-diameter cooling section at 1 atm, 35 C, and 60 percent relative humidity at 120 m/min. The air is cooled by passing it over a cooling coil through which cold water flows. The water experiences a temperature rise of 8 C. The air leaves the cooling section saturated at 20 C. Determine (a) the rate of heat transfer, (b) the mass flow rate of the water, and (c) the exit velocity of the airstream. Figure P14-80
9 Chapter 14, Problem 94E. Air enters an evaporative cooler at 14.7 psia, 90 F, and 20 percent relative humidity at a rate of 150 ft 3 /min, and it leaves with a relative humidity of 90 percent. Determine (a) the exit temperature of air and (b) the required rate of water supply to the evaporative cooler.
10 Chapter 14, Problem 102. Two airstreams are mixed steadily and adiabatically. The first stream enters at 32 C and 40 percent relative humidity at a rate of 20 m 3 /min, while the second stream enters at 12 C and 90 percent relative humidity at a rate of 25 m 3 /min. Assuming that the mixing process occurs at a pressure of 1 atm, determine the specific humidity, the relative humidity, the dry-bulb temperature, and the volume flow rate of the mixture. Figure P14-102
11 Chapter 14, Problem 112. A wet cooling tower is to cool 60 kg/s of water from 40 to 26 C. Atmospheric air enters the tower at 1 atm with dry- and wet-bulb temperatures of 22 and 16 C, respectively, and leaves at 34 C with a relative humidity of 90 percent. Using the psychrometric chart, determine (a) the volume flow rate of air into the cooling tower and (b) the mass flow rate of the required makeup water. Figure P14-112
