The upper surface of an ASME SB-96 copper-silicon plate is subjected to convection with hot air flowing at 6.5 m/s parallel over the plate surface. The plate is square with a length of 1 m, and the temperature of the hot air is 200°C. The ASME Boiler and Pressure Vessel Code (ASME BPVC. IV-2015, HF-=) limits equipment constructed with ASME SB-96 plate to be operated at a temperature not exceeding 93°C. From a wind tunnel experiment, the average friction coefficient for the upper surface of the plate was found to be 0.0023. In the interest of designing a cooling mechanism to keep the plate surface temperature from exceeding 93°C,

Determine the minimum heat removal rate required to keep the plate surface from going above 93°C. Use the following air properties for the analysis: cp = 1.016 kJ/kg*K, k = 0.03419 W/m*K, μ = 2.371×10^−5 kg/m*s, and rho = 0.8412 kg/m^3.
