Reconsider Prob. 170. Using EES (or other) software, plot the rate of heat transfer as a function

Question:

Reconsider Prob. 1–70. Using EES (or other) software, plot the rate of heat transfer as a function of the heat transfer coefficient in the range of 20 W/m²· K to 100 W/m²· K. Discuss the results.

Data from problem 70

Hot air at 80°C is blown over a 2-m × 4-m flat surface at 30°C. If the average convection heat transfer coefficient is 55 W/m²· K, determine the rate of heat transfer from the air to the plate, in kW.
