A tank, which is open to the atmosphere, is filled with water to a level h and allowed to drain through an orifice at the bottom, as shown in the

figure below. The cross-sectional area of the tank is At and the cross-sectional area of the orifice is Ag. Assume that the cross-sectional area of the tank is much greater than the cross-sectional area of the orifice (AT>>Ao) and that the exit losses are negligible. 6) Use Reynolds Transport Theorem to derive an expression for the variation of h with time as a function of velocity at the outlet.
