Question:

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 m2with 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).

Alr, 20°C T; = 250°C Steel Plate T, =?
