A transmission pipeline that conveys water from an upstream
reservoir to a downstream reservoir is indicated below. The
transmission main has a valve along its length that controls the
discharge in the system. The discharge through the valve is
computed with the valve equation below. The pipeline has a length
of 4,500 m, a Hazen-Williams 'C' factor of 110, and an inner
diameter of 450 mm. The upstream reservoir has a water level of 105
m. The valve discharge constant...

3) In the following pipe system, water discharge in pipe 1 is given as Qi=1.2 m3/s. The upstream and downstream reservoir water surface elevations are known, and they are Za=100 m, and ZB=80 m, respectively. Relevant pipe data are provided in the table below. Determine the diameter in pipe 3. Velocity head at the junction and minor losses in the system will be neglected. (v = 1 x 10-6 m2/s) | Pipe (mm) 3.6 ZA=100 m L (m) 5000 6000...
Question 15 As shown, water (15 °C) is flowing from a tank through a tube and then discharging to ambient. The tube has an ID of 12 mm, a length of L = 6 m, and the resistance coefficient is f = 0.015. The water level is H = 4 m. (a) Find the exit velocity in m/s. (b) Find the discharge in L/s. Assume that the only head loss occurs in the tube. H2O (a) v = m/s (b)...

2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...
B) A weir of 6 m long is to be built across a rectangular channel to discharge a flow of 7.5 m3/sec. If the maximum depth of water on the upstream side of weir is to be 1.5 m, what should be the height of the weir? Adopt Cd = 0.6.
06:20 marks) The water is flowing with a flowrate of Q= 0.5 m3/s in a pipe of length 1900 m, pipe diameter 600 mm and pipe thickness 16 mm. The pipe is elastic, bulk modulus of water Ep= 2.1 x10° N/m2, The modules of elasticity for the pipe material Ep = 3 x1011N/m2. At the end of the pipe, a valve is provide. Find the rise in pressure AP and pressure AH, if the valve is closed in 2.0 seconds.
Q3.) (2) point The pump at C produces a discharge of water at B of 0.035 m3/s. If the pipe at B has a diameter of 50 mm and the hose at A has a diameter of 30 mm, determine the power output supplied by the pump. Assume frictional head losses within the pipe system are determined from 3(VB)?/2g. B 30 m te
