A rectangular water tank is divided by a partition into two chambers,

A rectangular water tank is divided by a partition into two chambers, as shown in Fig. 17-23a. In the bottom of the partition is a round, sharp-edged orifice with a diameter of 150 mm. The coefficient of discharge for the orifice is 0.62. At a certain instant, the water level in chamber B is 2.5 m higher than it is in chamber A. How long will it take for the water surfaces in the two chambers to be at the same level? 2.5 Water Orifice 2.0 m 3.0 m -7.5m
