Moist air at 20°C, 1 atm, and 43% relative humidity and a volumetric flow rate of 900 m²/hrs. enters a control volume at steady state and flow along a surface maintained at 65°C, through which heat transfer occurs. Liquid water at 20°C is injected at a rate of 5 kg/hr and evaporates into flowing stream. For the control volume, Wev=0, and kinetic and potential energy effects are negligible. Moist air exits at 32°C, 1 atm. (a) draw the system schematic...

Moist air enters a duct at 10 °C, 80% relative humidity, and a volumetric flow rate of 150 m3/min. The mixture is heated as it flows through the duct and exits at 30 °C. No moisture is added or removed and the mixture stays at 1 atm. Determine the rate of heat transfer and the relative humidity at the exit.

Moist air at 24°C, 1 atm, and 35% relative humidity enters an evaporative cooling unit operating at steady state consisting of a heating section followed by a soaked pad evaporative cooler operating adiabatically. The air passing through the heating section is heated to 45°C. Next, the air passes through a soaked pad exiting with 50% relative humidity. Using data from the psychrometric chart, determine: (a) the humidity ratio of the entering moist air mixture, in kg(vapor) per kg(dry air). (b)...

Please answer the relative humidity
A humidifier takes in moist air at 29 °C, 1 bar, and 50% relative humidity with a volumetric flow rate of 13 m3/s. To increase the moisture of the air, liquid water at 40 °C is sprayed into the moist air witha flow rate of 22 kg/s. Some of the liquid water evaporates into the moist air stream and the rest drain:s out of the humidifier with a temperature of 26 °C and a mass...

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....

An air conditioner operating at steady state takes in moist air at 28ºC, 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 then passes through a heating unit, exiting at...

12.54 Air at 12°C, 1 atm, and 40% relative humidity enters a heat exchanger with a volumetric flow rate of 1 m'/s. A separate stream of dry air enters at 280°C, 1 atm with a mass flow rate of 0.875 kg/s and exits at 220°C. Neglecting heat transfer between the heat exchanger and its surroundings, pressure drops of ach stream, and kinetic and potential energy effects, determine (a) the temperature of the exiting moist air, in °C
