A 0.2-m-long and 25-mm-thick vertical plate
(k = 1.5 W/m⋅K) separates the hot water from the cold air at
2° C. The plate surface exposed to the hot water has a temperature
of 100° C, and the surface exposed to the cold air has
an emissivity of 0.73. Determine the temperature of the plate
surface exposed to the cold air ( T s, c ). Hint: The T s, c has to be
found iteratively. Start the iteration process with an initial
guess of 51° C for the T s, c .
