The discharge formula used in the design of the syphon well drop is ____________ Correct Answer 2.22H3/2 [L + 0.4nH

The discharge passing through a trapezoidal notch is given by adding the discharge of a rectangular notch and V-notch which is given by- Q = 2/3 Cd. (2g)1/2. L. H3/2 + 8/15 Cd. (2g)1/2. tan (Q/2). H5/2 Q = 2.22H3/2 (Where n = 2 tan (Q/2) and coefficient of discharge = 0.75).
