1(a) A rectangular notch is 1m wide. Water flows over this notch to a depth of 150mm. Then the same quantity of water passes through a triangular notch. What will be the height of water in the triangular notch? Take Cd for rectangular notch as 0.62 , Cd for triangular notch as 0.59 and Ɵ as 90°. (b) Water flows over a rectangular weir 3m long. The height of water surface over the weir is 1m. Calculate discharge over the weir by: Simple formula Francis’ formula Take Cd=0.62 and velocity of approach=2m/sec. Find the difference between the two discharges. (c) A rectangular tank of surface area 5m×5m contains water upto a depth of 4m. There is an orifice on the base of the tank of diameter 50mm. In how much time The level of water will fall to the depth of 2m The tank will completely empty Take Cd= 0.62

(b) Water flows over a rectangular weir 3m long. The height of water surface over the weir is 1m. Calculate discharge over the weir by:
- Simple formula
- Francis’ formula
Take Cd=0.62 and velocity of approach=2m/sec. Find the difference between the two discharges.
(c) A rectangular tank of surface area 5m×5m contains water upto a depth of 4m. There is an orifice on the base of the tank of diameter 50mm. In how much time
- The level of water will fall to the depth of 2m
- The tank will completely empty
Take Cd= 0.62
