A nozzle placed at the end of a water pipe line discharges water at a

If the depth of water in an open channel is less than the critical depth, the flow is called

The separation of flow occurs when the hydrodynamic boundary layer thickness is reduced to zero.

The error in discharge (dQ/Q) to the error in measurement of head (dH/H) over a triangular notch is given by

The discharge through a convergent mouthpiece is __________ the discharge through an internal mouthpiece of the same diameter and head of water.
