Consider laminar, fully developed flow in a channel
Chapter 8, Problem 8.87(choose chapter or problem)
Consider laminar, fully developed flow in a channel ofconstant surface temperature Ts. For a given mass flowrate and channel length, determine which rectangularchannel, b/a?1.0, 1.43, or 2.0, will provide the high-est heat transfer rate. Is this heat transfer rate greaterthan, equal to, or less than the heat transfer rate associ-ated with a circular tube?
