A hot plate of length 0.75 m, width 0.5 m, and thickness 2 cm is placed in an air stream at 20°C. It is estimated that a total of 300W is lost from the plate surface by radiation. Taking the convective heat transfer coefficient as 25 W/ m2K, and thermal conductivity of the plate as 43 W/mK, calculate the inside temperature of the plate.
