A system that consists of two interconnected cylindrical tanks with D1 = 30 cm and D2 = 12 cm is to be used to determine the discharge coefficient of a short D0 = 5 mm diameter orifice. At the beginning (t = 0 s), the fluid heights in the tanks are h1 = 45 cm and h2 = 15 cm, as shown in Fig. If it takes 200 s for the fluid levels in the two tanks to equalize and the flow to stop, determine the discharge coefficient of the orifice. Disregard any other losses associated with this flow.
