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.

Q_out = _____ kJ/min

(b) Determine the mass flow rate of the water. Round your answer to the nearest hundredth

m_{cooling water} = _____ kg/min

V₂ = _____ m/min
