3. Air at a dry bulb temperature of 40C and a wet bulb temperature of 20C is first heated in a heater to a dry bulb temperature of 90C. Then it is passed through a bed of apricot slices to dry them. The air exiting from the top of the apricot bed is at a dry bulb temperature of 60C. It is then passed through a dehumidifier to reduce its relative humidity to 10%. Clearly show the various paths of...

150 ft3/min of air at 80F dry-bulb temperature and 70% relative humidity enters an air conditioning unit and leaves it as saturated air at 50F. Part of the moisture in the air that condensate is collected and removed at 55F. Draw the cycle on the attached chart and a)Determine the rates of heat removal from the air. b)Determine the rate of moisture removal from the air

Atmospheric air enters a heating section of a duct at 1 atm, 10 °C (dry bulb), 40% relative humidity and a mass flow rate of 1.1 kg/s. An electrical resistance provides 4 kW of energy to the air. If the humidity ratio stays constant during the process, determine the exit temperature (dry bulb) and relative humidity of the air.

(10 pts) Six-thousand cubic feet per minutes (C.F.M.) of atmospheric air at 28°C (dry bulb) having a wet bulb temperature of 23°C is to be cooled in an air conditioning system. The air conditioning system lowers the dry bulb temperature of the air to 20° C. Cooling with dehumidification is accomplished using chilled water loop. The chilled water enters the loop at 5°C at a rate of 280 kg/min and experience a 5°C temperature increase. The atmospheric pressure is 1...

1. Wet solids pass through a continuous dryer. Hot dry air enters the dryer at a rate of 400 kg/min and mixes with the water that evaporates from the solids. Humid air leaves the dryer at 50°C containing 2.44 wt% water vapor and passes through a condenser in which it is cooled to 10°C. The pressure is constant at 1 atm throughout the system. a. At what rate (kg/min) is water evaporating in the dryer? b. Use the psychrometric chart...
