1. Water flows over a right angled V notch to a height of 0.2 m. Calculate the coefficient of discharge of the notch if the actual flow rate measured is 26.2 l/s.

2. Water flows at the rate of 106 l/ sec in a open channel in which rectangular and V notches are fitted. The width of the rectangular notch is 100 cm and the head of water over it is 0.15 m. If the V notches is right angled calculate the coefficients of discharge of both rectangular and V notches.
