- The reservoir tank shown contains fresh water air pressurized to 200 kPa. There is a loss of 3.3 N*m/N due to friction in the pipes. Point 1 is located at the surface of the water and point 2 is in the free stream of the exit spray. The Distance from the water surface to the free stream is 3 meters. The flowrate for the system is .05 m^3/s (Work on paper required) 1. How much energy is provided to the motor by the flowing water? 2.

A siphon has an uniform circular section of 70 mm diameter and consists of a bent pipe with its crest 1.6 m above the water level as shown in figure. The siphon discharges into the atmosphere at a level 3.0 m below the water level. Calculate the velocity of flow and the discharge. The absolute pressure at the end of the siphon is equivalent to 10 m head of water. Calculate the absolute pressure at the crest. Neglect all losses. 1.6 m 3.0 marrow_forward2. A 6 in. pipe, as shown in the figure, takes water from a reservoir and terminates in a nozzle having a jet diameter of 2 in. Assuming a nozzle loss of 8 percent of the velocity head in the jet, compute the discharge (in SI units). Also, make a table showing the elevation head, velocity head, pressure head, and total head at each of the six stations. Lastly, draw the hydraulic gradient line (H.G.L.) & the energy gradient line (E.G.L.). Head losses in pipe: 1 to 2: 3.00 m 2 to 3: 9.00 m 3 to 4: 4 to 5: 18.00 m 6.00 m 1 W.S.

The discharge pipe of a pump is 400 mm in diameter delivers 0.5 m3/sec of water to a building which maintains a pressure of 100 Kpa at a height of 30 m, what power must be furnished by the pump?arrow_forwardA vessel is being filled with water through an inlet at section 1 having a diameter of 40 mm and a faucet at section 3. The velocity at section 1 is given as 5 m/s, while the discharge at section 3 is given as 0.012 m^3/ s. Assume constant water level. Use 60 mm for the diameter of the outlet at section 2. A. What is the discharge at section 2? B. What is exit velocity at section 2? C.

- Water flows at a rate of 500 gal/min through a 400-ft-long line. The first and last 100 ft of the line are 6-in-diameter cast iron pipes, while the middle 200 ft consists of two 4.24-in-diameter cast iron pipes. Find: a. Provide a diagram b. the average velocity in each section of pipe, c. the pressure drop in each length of pipe, and d. the total pressure drop.arrow_forwardA pump draws water from reservoir A and lifts it to reservoir B as shown in figure 4. Elev. of water at reservoir A is 10m.The loss of head from A to 1 is 3 times the velocity head in the 150mm pipe and the loss of head from 2 to B is 20 times the velocity head in the 100mm pipe. Compute the horsepower output of the pump and the pressure heads at 1 and 2 when the discharge is 200gpm.arrow_forwardA horizontal 154 mm diameter pipe gradually reduces its section to 53 diameter, subsequently enlarging into 154 mm section. The pressure in the 154-mm pipe at a point just before entering the reducing section is 141 kPa and in the 53 mm section at the end of the reducer, the pressure is 73 kPa. If 627 mm of head is lost between the points where the pressure are known compute the rate of flow in L/s of water through the pipe.arrow_forward
- A pitot-static tube placed in the centre of a 300 mm pipe line has one orifice pointing upstream and other perpendicular to it. The mean velocity in the pipe is 0.80 of the central velocity Find the discharge through the pipe if the pressure difference between the two orifices 60 mm of water. Take the co-efficient of pitot tube as C, = 0.98.arrow_forwardFor the flow configuration shown, you are required to design a pump station to transfer water from the bottom tank to the upper tank. In your own words, explain the steps that are needed to be followed for the design of the pump system. Your answer should be typed and not more than one page. The pipe equivalent roughness is 1.5 mm. And a valve with a k=10 is located just upstream of the lower reservoir (other losses are negligible). Take p=1000 kg/m”, g = 9.81 m/s?, and u = 1.179 x 102 kg/m.s.arrow_forward3. In the following system, the flow rate of Q= 400 It/s is transmitted from the A chamber to the B chamber. There is a valve in the pipe where the diameter is large and there is a local loss due to the valve. Using the valve formula (K) as 10 (see formulas), calculate the distance H between the water face elevations of the two chambers. Draw the relative energy and piezometer lines.
