- If the rate of rotation speed of the 3-tube system shown below is w =10 rad/sec, determine the water heights in each tube leg. At what rotational speed will the middle tube be completely empty?A smooth transition section connects two open channels of the same width, as shown in Figure P10.15. The water depth decreases so that the ratio of the downstream to upstream depths Y2/Y1 = 0.5. If the upstream Froude number F1 = 0.35, determine the downstream Froude number F2, and the ratio h/Y1.In a rectangular channel 4m wide with Q=7.65m3/s the depth is 0.4m. If a hydraulic jump is produced, (a.) what will be the depth immediately after it? (b.) what will be the loss of energy?
- An excavation is proposed for a square area near the bend of a river, as shown in Figure P6.9. It is expected that the flow of water into the excavation will come through the silt layer. Pumping tests reveal an average horizontal hydraulic conductivity of 2 × 10-5 cm/s in the silt layer. The excavation has to be kept dry. Determine the flow (qt) into the excavation.Given Figure E1, draw the active earth pressure distribution. Use gw = 9.81 kN/m3. Determine the magnitude and location of the active thrust.1. Calculate the Froude angle for a flow of depth 0.102 m moving at 2 m/s. 2. Determine the minimum depth in a 3 m wide rectangular channel if the flow is to be subcritical with a flowrate of 30 m3/s. 3. Estimate the speed of a tsunami as it travels across the Pacific Ocean, given that the average depth of the water is about 2000 m. State your assumptions.
- A 20 m wide rectangular channel carries 100 m³/s of water at 1.0 m depth before entering a jump. Compute the critical depth and the downstream (sequent) water depth, and energy loss in the absence of friction.Suppose that a stable hydraulic jump forms between the two sluice gates shown in Figure 5.15. If the flow depth downstream of a sluice gate is 61% of the gate opening (yg), determine the downstream gate opening (yg2) for the following conditions: y1 = 0.61 m, Q = 15 m3/s, b = 5 m. (Hint. Assume no loss of energy through a sluice gate.)Read the question carefully and give me right solution with clear calculations. Note: If you don't know the solution please leave it but don't give me wrong solution. If the sequent depth equal to 1.7 m, and the energy dissipated =0.5 kg.m/kg of a hydraulic jump in a rectangular channel, what's the length of the jump?
- Someone pours a cup of water into an open well dug into a confined aquifer. If the piezometric head is 4m lower at the neighbors well 1500m away, how long will it take the poured water to travel to the neighbors well? Assume steady, unidirectional flow in a homogeneous silty sand confined aquifer with a hydraulic conductivity of 3.5 m day-1, and an effective porosity of 0.35.A 1.15 m diameter pumping well penetrates vertically through a confined aquifer which is 42 m thick. While pumping at a rate of 2880 m3/day, the drawdown in an observation well 20 m away is 2.0 m. In another observation well, that is located 60m away, the drawdown is 0.45m. Initial piezometric level is 52m above the datum. Determine: The radius of influence of the pumping well?A rectangular channel with a width of B = 2 m drains water with a discharge of Q = 2,4 m3/s. The depths of water at an adjacent point are 1,5 m and 1,4 m. If the Chezy coefficient is 50 and the slope of the Io channel base = 0,0004, calculate the distance between the two faces. Continue to normal depth with the direct step method.
