Consider a stainless steel spoon (k = 8.7 Btu/hrft°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 x 0.5 in, and extends 7 inches into 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/hrft²ºF, determine the temperature of the tip of the spoon handle. Assume that the heat loss from the tip of the spoon is negligible. Tair = 75°F Boiling water 200°F Spoon 7 in

Question
Consider a stainless steel spoon ( k = 8.7 Btu/hrft°F) partially immersed in boiling water at 200 deg * F in a kitchen at 75°F. The handle of the spoon has a cross section of 0.08in * 0.5in and extends 7 inches into 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/hrft²°F, determine the temperature of the tip of the spoon handle. Assume that the heat loss from the tip of the spoon is negligible.
Transcribed Image Text:Consider a stainless steel spoon (k = 8.7
