A 1:4 scale model of a water pumping station pumping system is to be tested to determine overall head losses 5. Air at 30 °C, 1 atm, is available. For a prototype velocity of 600 mm/s in a 3-m-diameter section with water at 20°C, determine the air velocity and quantity needed. How may losses determined from the model be converted into prototype losses?

Two parallel pumps are pumping water (p = 1000 kg/m) through very large diameter pipes of diameter D such that the friction losses in the piping and kinetic energy changes are negligible. The height between the elevation level d and the elevation level a is Had = 100 meters. The equation for the system resistance curve (SRC) is: Ap = pg Had The equation for each pump performance curve running at 1760 rpm is given by Ap = 981 +...

Problem 4 (50 points) Water is discharged from a reservoir at a rate of 18.103 m3/s using two horizontal cast iron pipes connected in series and a pump between them. The first pipe is 20 m long and has a 6-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged. Losses...

A 600mm diameter horizontal pipe of length 2km branches into two pipes of 300mm and 450mm diameter, each 1.6km long (Fig. Q5). The 600mm pipe is at an elevation of 30m and connects reservoir A with water level 50m. The two branched pipes connects reservoir B with water level 100m. A pump is installed in the 600mm pipe and causes the flow from A to B. Calculate the required power of the pump to maintain a flow rate of Im®/s...

Water to a residential area is transported at a rate of 1.5 m3/s via 70-cm-internal-diameter concrete pipes with a surface roughness of 3 mm and a total length of 1500 m. In order to reduce umping power requirements, it is pro posed to line the interior surfaces of the concrete pipe with 2-cm-thick petroleum-based lining that has a surface rough ness thickness of 0.04 mm. There is a concern that the reduc tion of pipe diameter to 66 cm and...

A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe is taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. In order to drain the tank faster, a pump is installed near the tank exit. Water tank Pump Required...

20. A cylindrical water tower of diameter 3.0 m supplies water to a house. The level of water in the water tower is 35 m above the point where the water enters the house through a pipe that has an inside diameter 5.0 cm. The pressure at the top of the water tower is I ATM and the water in the cylindrical tank flows slowly at a speed of 0.01 cm/s. At what speed does the water flow in the...

Water is slowly drained from a large reservoir using two horizontal plastic pipes connected in series. The pipes are smooth and located at the bottom of the reservoir, as shown below. The first pipe has a diameter D1 = 10 cm and length L1 = 10 m, while the second pipe has a diameter D2 = 5 cm and a length L2 = 40 m (see schematic below). The water level in the reservoir is constant and equal to H...
