Question
Heating Air by a Steam Heater. A total of 13 610 kg/h of air at 1 atm abs
pressure and 15.6°C is to be heated by passing over a bank of tubes in which
steam at 100°C is condensing. The tubes are 12.7 mm OD, 0.61 m long, and
arranged in-line in a square pattern with S, = S, = 19.05 mm. The bank of
tubes contains 6 transverse rows in the direction of flow and 19 rows normal to
the flow. Assume that the tube surface temperature is constant at 93.33°C.
Calculate the outlet air temperature.
