A thin metal sheet serving the purpose of an an anemometer has a length of 2.5 cm with a width of 8 mm. Wind with a temperature T, and velocity U, blows parallel to the longest side of the sheet. The metal sheet is heated through a solar powered system giving our heat both sides at Q Watts. The anemometer is used in air with T-= 20C, C, = 1.005kJ/Kg K, v = 1.522 X 10 m/s, p = 1.19 Kg/m² and Pr= 0.72. The surface temperature, T, of the metal sheet was measured at the rear end however, it can be assumed to be constant. You are required to calculate an estimate of the wind speed when T. = 32°C and Q = 0.5 W.
