Air at 95°F, 1 atm, and 10% relative humidity enters an evaporative cooler operating at steady state. The volumetric flow rate of the incoming air is 1765 ft3/min. Liquid water at 68°F enters the cooler and fully evaporates. Moist air exits the cooler at 70°F, 1 atm. There is no significant heat transfer between the device and its surroundings and kinetic and potential energy effects can be neglected.

a)Determine the mass flow rate of the dry air in lb(dry air)/min.

b)the relative humidity at the exit

c)the dew point temperature at the exit

Moist air at 30 °C and 50% relative humidity enters a dehumidifier operating at steady state with a mass flow rate of 319.35 kg/min. The moist air passes over a cooling coil and water vapor condenses. Condensate (condensed water) exits at 10 °C. Saturated moist air exits in a separate stream at the same temperature. The pressure remains constant at 1 bar. Determine (a) the rate at which water is condensed, in kg/min, and (b) the heat transfer rate during...

Atmosphric air at 40 F and 50% relative humidity enters the heating section of an airconditioning device at a volumetric flow rate of 100ft^3/min. Water vapor is added to the heated air to increase the relative humidity to 55%. The temperature after the heating section is 72F and the temperature at the exit is 74F. Using the appropriate fomulas: a) determine the rate of the heat transfer in Btu/min. b) determine the mass flow of water vapor in lbm/min.
