5. Air at 20°C with a convection heat transfer coefficient of 25 W/m². K blows over a horizontal steel hot plate (k = 43). 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 = 250°C and the plate loses 300 W from its surface by radiation. Calculate the inside plate temperature (Ti). I Ti Ti = 253.0416°C
