Water at 43.3°C flows over a large square plate at a velocity of 20 cm/s. The plate is 2 m long (in the flow direction) and its surface is maintained at a uniform temperature of 10.0°C. The width of the plate is 2 m. Calculate the steady rate of heat transfer for the entire width of the plate in watts (W). The properties of water at the film temperature of (Ts+ To)/2 = (10 + 43.3)/2 = 27°C are p = 996.6 kg/m3, k= 0.610 W/m-°C, u= 0.854 x 10-3 kg/m-s, and Pr = 5.85. The steady rate of heat transferlper unit width of the plate is W.

Water at 43.3°C flows over a large square plate at a velocity of 20 cm/s. The plate is 2 m long (in the flow direction) and its surface is
maintained at a uniform temperature of 10.0°C. The width of the plate is 2 m. Calculate the steady rate of heat transfer for the entire
width of the plate in watts (W). The properties of water at the film temperature of (Ts+ To)/2 = (10 + 43.3)/2 = 27°C are p = 996.6
