Problem 4

bottom, where water discharges to the atmosphere. The water
level is 2.5 m above the outlet. The tank air pressure above the
water level is 250 kPa (absolute) while the atmospheric pressure is
100 kPa. Neglecting frictional effects, determine the initial
discharge rate of water from the tank.

Reservoir A is at elevation 240m. From Reservoir A, a 450mm pipe, 600m long connects to point B at elevation 210m. The discharge on this 450mm diameter pipe is 200 liters/second. At point B, it divides into a 300mm pipe, 3900 m long to Reservoir C at elevation 195m and into Reservoir D at elevation 135m, which is 1200m long. Neglecting minor losses in the pipes, calculate the diameter (in mm) of the pipe that discharges into Reservoir D. Use f = 0.02 for all pipes. Round off your answer to a whole number.
Tank A has an elevation of 100 m and Tank B has an elevation of 160 m. Since Tank A is lower than B, engineers have installed a pump near A to transfer fluid to B. The discharge in the pipe is at 0.65 cubic meters per second and pipe has a length of 1 km. with a diameter of 0.6 meters. If Hazen williams coefficient is equal to 120, compute the head loss in the pipe.
A pipe is carrying 3.26x10-4 m³/s of flow. If C=100, diameter=25 mm, length=21 m. Determine the head loss in this pipe.
Two pipes link two reservoirs (A and B) that are 15m apart in height. Pipe 1 is 60 mm wide and 100 m long. Pipe 2 is 90m long and has a 90mm diameter. Entry loss k = 0.6, exit loss k = 1.0, and f = 0.008 are the same for both. Calculate: 1. How much water flows through each pipe 2. The diameter D of a pipe 100m long that could replace the two pipes and have the same flow.
A 170-m long pipeline, composed of two pipes connected in series, discharges freely at a point 40 m below the water level at intake. The pipe projects into the reservoir. The first 100 m is 25 cm in diameter, and the remaining 70 m is 15 cm in diameter. Assuming that f=0.05 for both pipes, (a) find the rate of flow. If the junction of the two sizes of pipe is 25 m below the intake water-surface level, find the pressure head just above C and just below C, where C denotes the point of junction. Assume a sudden contraction at C. Use k=0.8 for entrance, 0.24 for sudden contraction and 1.0 for exit. I will downvote the incorrect solution
Water from a Reservoir through a main canal is connected to a branch canal over an embankment by means of tube of 90 mm diameter. The length of pipeline up to the summit is 25 m and the total length is 65 m. Entry loss may be assumed as one-half of the velocity head in the pipe. Assume friction factor, f = 0·03. Water surface elevation in the branch canal is 10 m below that of the main canal. If the total quantity of water required to be conveyed is 0·06m3 /s, how many pipelines are needed for effective delivery of water ? What is the maximum permissible height of the summit above the water level in the main canal so that the water pressure at summit may not fall below 20 kN/m2? Explain the losses that were encounted when the water was flowing through the tube. ( absolute, thebarometric reading being 10 m of water)

The diameter of a pipeline at point 1 is 75 mm and at point 2 is 25 mm. Points 1 and 2 are at the same elevation. The liquid (sp.gr. = 1.4) on the pipeline discharges at point 2 into the atmosphere. Compute the velocity head of the jet if the pressure head at point 1 is 50 meters of the liquid flowing, and the lost head between points 1 and 2 is 15 per cent of the velocity head at point 2.
Water flows from left to the right reservoir at a rate of 16 ft3/s (cfs). The head loss can be calculated as hL = 0.02(L/D)(V 2/2g), where L is the length of a pipe and D is the diameter. Determine the water surface elevation of the left reservoir.

Three reservoirs are connected at a junction, P, as shown. Reservoir A, whose surface elevation is at 60.0 metersfrom a given datum, discharges water at a rate of Q1 to junction P. Reservoir B, whose surface elevation is at 20.0m, then receives water from the junction at a rate of Q2, while Reservoir C, whose surface elevation is at 0.0 m,then receives water from the same junction at a rate of Q3. The head loss as fluid travels through the pipe fromreservoir A to the junction is hL1. The head loss as the fluid travels from the junction to reservoir B is hL2 and thehead loss as the fluid travels from the junction to reservoir C is hL3. (a) Setup the continuity equation at the junction.(b) What is the total head loss, in meters (give the numeric value), as water travels from reservoir A to reservoir B?(c) Similarly, what is the total head loss, in meters (give the numeric value), as water travels from reservoir A toreservoir C?
