Answer the Following Question.
With 7 kg/s of return air at 25°C and 50% relative humidity before entering a heating and humidifying device. The sensible heat factor of the device is 0.7 and the supply air temperature to the conditioned space is 35°C. Sketch the process on the psychrometric chart and find:
1. The capacity of the heating coil
2. The amount of moisture added
m = 7 kg/s Return Air
