Reconsider Prob. 20€“18. Using an appropriate software, evaluate the effect of the plate thickness on the surface temperature exposed to the cold air. By varying the plate thickness from 0.01 to 0.1 m, plot the plate surface temperature on the cold air side as a function of the plate thickness.

Reconsider Prob. 20€“18.

A 0.2-m-long and 25-mm-thick vertical plate (k = 1.5 W/mˆ™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).
