Each gate of the lock is 6 m high and is supported by two hinges placed on the top and bottom of the gate. When the gates are closed, they make an angle of 120º. The weight of the lock is 5 m. If the water levels are 4 m and 2 m upstream and downstream, respectively, determine the magnitude of forces on hinges due to the water pressure.
Question 5 A submerged sharp crested weir 0.8 m high stands clear across a channel having vertical sides and a width of 3 m. The depth of water in the channel of approach is 1.25 m and 10 m downstream from the weir, the depth of water is 1 m. Determine the discharge over the weir in liters per second. Take Cd as 0.6
Question 4 B A rectangular sharp crested weir is to be constructed in a testing station with a small stream in which the discharge varies from 50 liters/s and 1250 liters/s. Find the suitable length of the weir, if the minimum head to be measured is 50 mm and the maximum head on it does not exceed one-third of its length.
