Example 8.6 shows that, for two cylinders of the same length, diameter, and temperature, the horizontal pipe transfers away more heat than the vertical one. In this problem, we investigate the eff ect of diameter. Repeat the calculation of convection coeffi cient for the horizontal pipe of the example for diameters of 13, 17, and 19 cm.
