Air enters a 30-cm-diameter cooling section at 1 atm, 35 C, and 60 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 8 C. The air leaves the cooling section saturated at 20 C.
(a) Determine the rate of heat transfer. Round your answer to the nearest tenth.
Qout = _____ kJ/min
(b) Determine the mass flow rate of the water. Round your answer to the nearest hundredth
mcooling water = _____ kg/min
(c) Determine the exit velocity of the airstream. Round your answer to the nearest ones place.
V2 = _____ m/min
