Air at 20°C with a convection heat transfer coefficient of 25 W/m2 K blows over a horizontal steel hot plate (k = 43 W/m-K). The surface area of the plate is 0.38 m² with a thickness of 2 cm. The plate surface is maintained at a constant temperature of Ts=345°C, and the plate loses 300 W from its surface by radiation. Calculate the inside plate temperature (T). Air, 20°C T, Steel Plate T₁ = ? The inside plate temperature is °C.

Calculate the rate of flow of waste thermal energy out of the engine in the exhaust gases in kW (to 1 decimal point). If the air inlet temperature is 35 °C, the air to fuel ratio is 10:1, the inlet air mass flow rate is 37 kg/hr, the specific heat capacity of exhaust gas is 1.13 kJ/kg/K, and the exhaust temperature is 500 °C.
