Question:
Local overall heat transfer coefficient. In Problem 14A.1 the thermal resistances of the condensed steam film and wall were neglected. Justify this neglect by calculating the actual inner-surface temperature of the tubes at that cross section in the exchanger at which the oil temperature is 150°F. You may assume that for the oil hloc is constant throughout the exchanger at 190 Btu/hr ∙ ft2 ∙ F. The tubes are horizontal.
