Question
Water is being discharged from a reservoir under a sluice gate at the rate of 10m into a horizontal
rectangular channel, 3m wide, made of unfinished formed concrete. At a point where the depth is
Im, a hydraulic jump is observed to occur. Determine the following:
a. The velocity before the jump
b. The depth after the jump
c. The velocity after the jump
d. The energy dissipated in the jump.
Sluice gate
y₁ = 1 m
87
The attached table is required to select design data required to estimate the flow
rates for a long-throated flume with different Head (H). It is well-known that the flow rate falls
within a range of 6.0 to 9.0 ft³/s. Consider a rectangular, a trapezoidal, and a circular channel.
Use a head range between 0.2ft to 0.5ft and an interval of 0.1 ft. Estimate the discharge values.
