A total of 13,610 kg/h of air at 1 atm abs pressure and 15.6C is to be heated by passing over a bank of tubes in which steam at 100C is condensing. The tubes are 12.7mm OD, 0.61 m long, and arranged in-line in a square pattern with Sp=Sn= 19.05mm. The bank of tubes contains six transverse rows in the direction of flow and 19 rows normal to the flow. Assume that the tube surface temperature is constant at 93.33C. What is the outlet air temperature?
