Air at 20C with a convection heat transfer coefficient of 25 W/m2K

Air at 20C with a convection heat transfer coefficient of 25 W/m2K 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 = 250C and the plate loses 300 W from its surface by radiation. Calculate the inside plate temperature (Ti). FIGURE P1-96 Air, 20C T, = 250C Steel Plate T; = ?
