Repeat Prob. 10–118E for a silver spoon (k = 247 Btu/h · ft · °F).
Problem 10-118E
Consider a stainless steel spoon (k = 8.7 Btu/h· ft· °F) partially immersed in boiling water at 200°F in a kitchen at 75°F. The handle of the spoon has a cross section of 0.08 in 0.5 in, and extends 7 in in the air from the free surface of the water. If the heat transfer coefficient at the exposed surfaces of the spoon handle is 3 Btu/h· ft2· °F, determine the temperature difference across the exposed surface of the spoon handle. State your assumptions.
