Reconsider Prob. 3103. Using EES (or other) software, plot the rate of heat transfer from the ball
Question:
Reconsider Prob. 3–103. Using EES (or other) software, plot the rate of heat transfer from the ball as a function of the plastic insulation thickness in the range of 0.5 mm to 20 mm. Discuss the results.
Data From problem 103
A 5-mm-diameter spherical ball at 50°C is covered by a 1-mm-thick plastic insulation (k = 0.13 W/m · K). The ball is exposed to a medium at 15°C, with a combined convection and radiation heat transfer coefficient of 20 W/m2 · K. Determine if the plastic insulation on the ball will help or hurt heat transfer from the ball.
