Water from a low dam is released through a sluice gate on a horizontal rectangular channel. The depth of water upstream of the sluice gate is 16.0 m above the channel bed andthe gate opening is 1.5 m. The sluice gate can be assumed to be sharp-edged. If a freehydraulic jump is formed just downstream of the gate, fi nd the sequent depths and thepercentage of the initial energy lost in the jump.
