) ⋅ Wtube ⋅ Lt (10)The tube wall temperature was required in order to determine the effect of the air side fins onheat transfer. The tube wall temperature was calculated from a heat balance on the outer surfaceof the ethylene glycol tubes: Qin ,tube − Qout ,tube + Q gen,tube = Qacc,tube (11)There was no heat generated on the surface of the tubes, and the temperature of the tube wall isessentially constant, making the accumulated heat negligible. The heat into the tube wall is dueto convection with the air, shown as: “Proceedings of the 2007 Midwest Section Conference of the American Society for Engineering Education
