A partially open sluice gate discharges water into a rectangular channel. The tail water depth in the channel is 3m and Froude number is 1/2/2. If a free hydraulic jump is to be formed at downstream of the sluice gate after the vena contracta of the jet coming out from the sluice gate, the sluice gate opening should be (coefficient of contraction Cc = 0.9)

For the 2D duct below, determine the stream function using 4x = 4y = 0.1 m. 3 m 2 m/s ► ► → 5 m 2m 1m

What is the volumetric flow rate through at 4 inch (10 cm) diameter pipe containing chocolate milk p = 1010 kg/m³, u= 0.00202 Pa.s). Along this section of pipe, there are two 90° pipe bends (K = 0.2) and a fully open gate valve (K = 0.1). The average roughness height of the pipe is ɛ = 0.1 mm. You measure the pressure at the two gauges shown below and find that the pressure decreases between them by 802.8 kPa. -1m- Valve -1m- What is the volumetric flow rate through this section of piping? -6→

An overflow spillway is 40 m high. Water flows down the spillway with a head of 2.5m over the spillway crest. The spillway discharge coefficient Ca = 0.738. Show that the water depth at the toe of the spillway would be 0.3 m. Determine the sequent depth required for the formation of the hydraulic jump and the loss of head in the jump.
