Problem 3 You move to Tempe Arizona on co-op and have the enviable job of analyzing an evaporative cooler for outdoor shops. Air flows enter evaporative cooler at 17 m/min, 40°C, and 10% relative humidity. Liquid water also at 40°C is sprayed into the airstream at 0.15 kg/min. Assume all the water evaporates. Determine: (a) the mass flow rate of dry air in kg/min (b) the humidity ratio of the moist air exiting (c) the enthalpy of the moist air...

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 895 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....

On a typical autumn day, outside air with a dry bulb temperature of 15°C and 40% relative humidity is brought into a processing facility where it is to be used for a controlled storage chamber. The air must be heated to 37°C and humidified to 90% relative humidity. Calculate: (11 marks total) The relative humidity of the air when it is heated to 37°C, but BEFORE it is humidified. (No water has been added to the air yet). (2 marks)...

Problem 3 Part a P=57 Moist air enters the cooler of an air conditioning unit at 25 °C and a relative humidity of 70%. The cooled and dehumidified air leaves the cooler saturated at 18 °C. The temperature of condensed water is 18 °C. The pressure is constant at 101.325 kPa. The mass flow rate of the dry air is mda=67 kg/s. Use the psychometric chart to determine a) The humidity ratio at the...

QUESTION 1 [15 marks] Due: 5 August 2020 An air conditioner operating at steady state takes in moist air at 28°C, 1 atm and 70% relative humidity. The moist air first passes over a cooling coil in the dehumidifier unit and some water vapor is condensed. The rate of heat transfer between the moist air and the cooling coil is 38.69 kW. Both saturated moist air and condensate streams exit the dehumidifier unit at the same temperature. The moist air...
