Determine the rate of convection heat loss from both the top andthe bottom of a flat plate at Ts = 80°C with airin parallel flow at T? = 25°C, u? = 3 m/s. Theplate is t = 1 mm thick, L = 25 mm long, andw = 50 mm deep. Neglect the heat loss from the edges ofthe plate. Compare the rate of convection heat loss from the plateto the rate of convection heat loss from an Lc =50ÂmmÂlong cylinder of the same volume as that of the plate. Theconvective conditions associated with the cylinder are the same asthose associated with the plate.
ANSWER: 5.84 W, 3.73 W
