3. Find the discharge through a totally drowned orifice 3 m wide and 1 m deep, if the difference in water levels on both the edges of the orifice is 2 m. Coefficient of discharge is 0.65. 4. The head of water over an orifice of diameter 100 mm is 5 m. The water coming out form the orifice is collected in a circular tank of diameter 2 m. The rise of water level in circular tank is 0.45 m in 30 seconds. Also the coordinates of a certain point on the jet, measured from the vena contracta are 1 m horizontal and 0.052 m vertical. Find the hydraulic coefficents.
