Consider steady heat transfer between two large parallel plates at constant temperatures of T1 = 300 K and T2 = 200 K that are L = 1 cm apart, as shown in Fig. 1–44. Assuming the surfaces to be black (emissivity ε = 1), determine the rate of heat transfer between the plates per unit surface area assuming the gap between the plates is (a) filled with still air with k= 0.0219 W/m°C, (b) free flowing air with h= 7.5 W/m^2°C, (c) evacuated
