Steаm аt аtmоspheric pressure is being cоndensed in an air-cоupled heat exchanger containing 500 fins. The assembly is 1 m long and 0.2 m deep, and the air channels are 20 mm wide. The fins are made of aluminum (k = 200 W/m-K) and are 0.1 mm thick. The air temperature is at 25oC, with a heat transfer coefficient of 35 W/m2-K. Assume that the exterior of the assembly is fully insulated. a) Calculate the minimum temperature of the aluminum fin and determine its location. b) How much heat do all the fins transfer? c) How much heat does the entire assembly (fins and tube walls) transfer? d) How much heat would the entire assembly transfer if the fins were perfect? (20 min, 30 points)
