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 Ibm(dry air)/min. B. Determine the mass flow rate at which liquid enters in Ibm(water)/min.. C. Determine the mass flow rate of the moist air at the inlet. D. Determine the relative humidity at the exit.
