Wind flows over a flat plate of length L = 25 mm and width W = 8 mm. The plate is maintained at a constant temperature of 32 °C on both sides using an electric heater generating heat at a rate of Q = 0.5 W which is dissipated to air from both sides of the plate. Consider the temperature of the wind/air as 20 °C and assume that the wind speed does not exceed 100 m/s. %3D The properties of air at this temperature are given as; specific heat capacity C, = 1.005 kJ/kg-K, thermal conductivity k = 0.0253 W/m- %3D K, Density p = 1.19 kg/m³, and kinematic viscosity v = 1.522 x 10-5 m²/s. If Prandtl number, Pr= 0.72, determine the average convective heat transfer coefficient. 52 W/m2-K 104 W/m2-K
