One end of a 9-in long × 7-in diameter copper bar is heated to 59.4°F, the far end of the bar is held at 23°C. If the sides of the bar are covered with thermal insulation, what is the rate of heat transfer?
Step-by-Step
Heat=\frac{220\times 3.14\times 7\times 7\times 36.4\times 12}{4\times 12\times 12\times 9} \ BTU/h=2852.11 \ BTU/h
