Cooling water flows over a hot metal plate with a surface area of 0.5 m2 in a manufacturing process. The temperature of the cooling water is 15°C, while the metal plate’s surface temperature is maintained at 200°C. If the convective heat transfer rate is 68.0 W/m2-K, determine the rate of convective heat transfer from the plate.
Given: A = 0.5 m2; Tf = 15°C; Ts = 200°C; h = 68.0 W/m2-K
