Repeat Problem 8.106 if the downspout is circular.

Problem 8.106

Rainwater flows through the galvanized iron downspout shown in Fig. P8.106 at a rate of \(0.006 \mathrm{~m}^{3} / \mathrm{s}\). Determine the size of the downspout cross section if it is a rectangle with an aspect ratio of 1.7 to 1 and it is completely filled with water. Neglect the velocity of the water in the gutter at the free surface and the head loss associated with the elbow.
