Q. A rectangular orifice of 2 m width and 1.2 m deep is fitted in one side of large tank. The easier level on one side of the orifice is 3m above the top edge of the orifice while on the other side of the orifice the water level is 0.5 m below it’s top edge. Calculate discharge if Cd = .64

View solution

Q. The time taken to empty the tank is independent of Cd but depends only on the height and acceleration due to gravity.

View solution

Q. The discharge rate is independent of the height difference and dependent only on the height.

View solution

Q. In case of submerged orifice the discharge is substantially dependent on temperature of fluid.
