Consider the long rectangular bar of Problem 4.50 with the prescribed boundary conditions.

(a) Using the finite-element method of FEHT, determine the temperature distribution. Use the View/Temperature Contours command to represent the isotherms. Identify significant features of the distribution.

(b) Using the View/Heat Flows command, calculate the heat rate per unit length (W 1m) from the bar to the air stream.

(c) Explore the effect on the heat rate of increasing the convection coefficient by factors of two and three. Explain why the change in the heat rate is not proportional to the change in the convection coefficient.
