A river channel that is rectangular in shape, with a bed width of $5\mathrm{.}0$ m$,$ carries a flow of $25\mathrm{.}9$ m$3/$s$.$ A long the way and due to abrupt changes in slope, a hydraulic jump is formed in the channel resulting in a flow depth of $2\mathrm{.}25$ m after the jump. For this condition, calculate the energy that is 'lost' as a result of the turbulence at the hydraulic jump. Select ONE.
