Question

In deriving the equation for the hydraulic jump in the rectangular channel in terms of the conjugate depths and the initial Froude Number,

• A. continuity equation and momentum equation are used
• B. continuity equation and energy equation are used
• C. gradually varied flow equation is used
• D. equations of continuity, momentum and energy are used

Answer 1

The correct option is A continuity equation and momentum equation are used

The energy loss $E_L$ in the jump is obtained by using the energy equation also.
