A tank of water 1 m deep, 3 m long and 4 m wide into the paper has a closed sluice gate on the right side, as in Fig. P10.75. At t = 0 the gate is opened to a gap of 10 cm. Assuming quasi-steady sluice-gate theory, estimate the time required for the water level to drop to 50 cm. Assume free outflow.
