The flow rate of water in a 6-m-wide rectangular channel is to be measured using a 1.3-m-high sharp-crested rectangular weir that spans across the channel. If the head above the weir crest is 0.70 m upstream from the weir, determine the flow rate of water.

Q4: The flow is occurring in a rectangular channel at a velocity of (571/500) m/sec and a depth of 0.2 m. Neglecting the effect of the velocity of approach & applying the relation; Q=1.84*L*H3/2, Analyze that what should be the height of a sharp-crested weir that mustbe installed to raise the water depth upstream of the weir to 1.2 m.

The tank shown drains through a triangular weir whose flowrate is described by the equation given. Determine the time it will take for the tank to drain from completely full (h = 5 ft) to 5.25 feet deep (h = 0.25 ft) assuming there is no flow into the tank. Volumetric Flowrate h=5 ft + 5 ft 3 ft³ S = 2.48 h².5 (for h in feet) 10 ft -20 ft- -20 ft-

Water flowing in a wide channel at a flow depth of 45 cm and an average velocity of 6.5 m/s undergoes a hydraulic jump. Determine the fraction of the mechanical energy of the fluid dissipated during this jump.
