A series of experiments were conducted by passing 40°C air over a long 25-mm-diameter cylinder with an embedded electrical heater. The objective of these experiments was to determine the power per unit length required to maintain the surface temperature of the cylinder at 300°C for different air velocities (V). The results of these experiments are given in the following table:
(a) Assuming a uniform temperature over the cylinder, negligible radiation between the cylinder surface and surroundings, and steady-state conditions, determine the convection heat transfer coefficient (h) for each velocity (V). Plot the results in terms of h (W/m2•K)?vs. V (m/s). Provide a computer-generated graph for the display of your results, and tabulate the data used for the graph.
(b) Assume that the heat transfer coefficient and velocity can be expressed in the form h = CVn. Determine the values of the constants C and n from the results of part (a) by plotting h vs. V on log-log coordinates and choosing a C value that assures a match at V = 1 m/s and then varying n to get the best fit.
It is calculated that a house requires 18,500 brick to complete its brick veneer facade. The contractor's experience indicates that it takes 4% more than the calculated amount to complete. If 4% more bricks are needed, how many more bricks than the 18,500 will it take to complete the job?
