Webfalse. the max temp difference in a heat exchanger is the temp difference between the inlet of hot and the inlet of cold. true. the maximum possible heat transfer rate in a heat exchanger is always limited by mass flow rate and heat capacity of the hotter fluid. false. WebFigure 1.19 In a fireplace, heat transfer occurs by all three methods: conduction, convection, and radiation. Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room, but much slower. Heat transfer by convection also occurs through cold air entering the room around ...
