A rectangular notch 1 m long and 40 cm high is discharging water. If the same quantity of water be allowed to flow over a 90° V-notch, find the height to which water will rise above the apex of notch. Cd = 0.62. B)_ Water flow over a right-angled V-notch under a constant head of 25 cm. 1- Find the discharge. 2- Using principles of geometric similarity find the head required for a flow of 1417.6 lit/s through the same notch. Cd = 0.62 C) A sharp-edge 90° V-notch is inserted in the side of a rectangular tank 3 m long and 1.5 m wide. Find how long it will take to reduce the head in tank from 30 cm to 7.5 cm if the water discharges freely over the notch and there is no inflow into the tank. Cd = 0.62.
