A heat exchanger is under development for purposes of heating liquid mercury. The exchanger can be visualized as a 6 in. long and 1 ft wide flat plate. If the plate is maintained at 160?F and the mercury flows parallel to the short side at 60?F and a velocity of 1 ft/s, find(a) The local friction coefficient at the middle point of the plate, and the total drag force on the plate.(b) The temperature of the mercury at a point 4 in. from the leading edge and 0.05 in. from the surface of the plate.(c) The Nusselt number at the end of the plate.GIVENMercury flowing over a flat plateTemperature of mercury (T??)) = 60?FVelocity (U??)) = 1 ft/s = 3600 ft/hrPlate length (L) = 6 in = 0.5 ftPlate width = 1 ftPlate surface temperature (Ts) = 160?FASSUMPTIONSSteadystate
