The depth of fluid following a hydraulic jump can be determined from an application of conservation of mass and conservation of momentum as discussed in Chapter 11.

This change in height must also result in a loss of available energy (lost work) across the jump. Apply the macroscopic mechanical energy balance to the system shown in Figure P11.16 to derive the loss expression:

\[\operatorname{loss}=\frac{g\left(h_{2}-h_{1}\right)^{3}}{4 h_{1} h_{2}}\]
