The top surface of a metal plate (kplate = 237 W/m?K) is being cooled by air (kair = 0.243 W/m?K) while the bottom surface is exposed to a hot steam at 100A????1C with a convection heat transfer coefficient of 30 W/m2?K. The bottom surface temperature of the plate is 92A????1C.
Given:
The thermal conductivity of air is given as kair = 0.243 W/m?K.
The thermal conductivity of the plate is given as kplate = 237 W/m?K.
Determine the temperature gradient in the air.
