Water flows through a triangular weir into a lower tank that has a 6.25-cm hole at the bottom. The level of the water in the upper tank is 0.15 m. If the flow rate at the weir equals to the rate of the hole, determine the height of the water in the lower tank (h). Given that the discharge coefficients of the weir and the hole is 0.59 and 0.61 respectively. an (2.10 m) A 0.59 Fre IF 0.15 m 6.25 cm -0.61
