Consider a pond of circular shape, radius R and width B (the width measured in the direction normal to the plane of the sheet). A pipe emerges from the bottom of the pond connected to a pump. This equipment sucks water at a flow rate Q = Kh2, where K is a constant and h(t) the height of the liquid contained in the pond at any instant t. Assume that the pond is initially full (h(0) = R). Determine algebraically the time T it takes for the system to empty.
