Question: Compute analysis of Prob. with qg= f(x) and constant fluid properties: Calculate the flow, starting with inital conditions of flat velocity and temperature profiles at the inlet. Compare the computer results with the analytical results.

Problem: Consider the flow of first air (Pr = 0.7) and then mercury (Pr = 0.01) at a Reynolds number of 100,000 in a 2 cm diameter circular tube with constant heat rate per unit of length. At a distance of 1.25 m from the tube entrance the heating stops, and the tube is insulated from then on. Using relative units of temperature; calculate and plot the decay of surface temperature as it approaches the mean fluid temperature in the insulated region. Discuss the difference in behavior of the two fluids in terms of the basic mechanisms involved.
