2 Prelab Consider an electrically heated horizontal flat plate in the laboratory with T= Tsur = 24C. The plate is well insulated at its lower surface and along its edges as illustrated in Fig. 7.1 of the text (page 435). The exposed surface at the top is black painted (surface has an emissivity 1) and has dimensions 3.00 in 3.00 in (76.2 mm 76.2 mm). Consider a test in the laboratory in which air flows over this surface with free stream temperature T = 24C and with a particular free stream velocity u. Under steady state conditions, the plate temperature is measured and found to be TS = 75C when the measured electrical input power is 24 W
