A gutter pipe removing rainwater from a building has a diameter of 4 inch and a total height and length of 12 ft . If the gutter is full, estimate the flowrate of draining. Assume a smooth pipe. With the Bernoulli equation, use the same velocity (equal to the velocity in the pipe) in the inlet and outlet reference points (unlike the example problem, where it was assumed the velocity at the inlet reference point was negligible).
