Air enters a 40-cm-diameter cooling section at 1 atm, 32C, and 70 percent relative humidity at 120

Question:

Air enters a 40-cm-diameter cooling section at 1 atm, 32°C, and 70 percent relative humidity at 120 m/min. The air is cooled by passing it over a cooling coil through which cold water flows. The water experiences a temperature rise of 6°C. The air leaves the cooling section saturated at 20°C. Determine

(a) The rate of heat transfer

(b) The mass flow rate of the water

(c) The exit velocity of the airstream.Water T T+ 6°C Cooling coils 32°C 20°C 70% 120 m/min Saturated Air
