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...

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...

Water, with density of 1000 kg/m3 and kinematic viscosity of 1.0 x 10- m2/s, is pumped through a total length of 60 m of pipe from a lower reservoir to a higher reservoir. The inner diameter of the pipe is 30 cm. Both reservoirs are open to the atmosphere, and the water surface of the higher reservoir is 10 m above that of the lower reservoir. The entrance from the lower reservoir to the pipe is sharp-edged, and along the...
Question 11 Water is flowing through a 10-cm-diameter water pipe at a rate of 0.2 m3/s. Now a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water that exits into atmosphere, as shown. Disregarding frictional effects, determine the force exerted on the flange due to the water flow. Density of water = 1000 kg/m3 = 10 cm D = 20 cm Diffuser 357 N 1549 N 6205 N none of...

Water at 15°C (ρ = 999.1 kg/m3and μ = 1.138 × 10−3 kg/m·s) is flowing
steadily in a 34-m-long and 6-cm-diameter horizontal pipe made of
stainless steel at a rate of 10 L/s. Determine the pressure drop,
the head loss, and the pumping power requirement to overcome this
pressure drop. The roughness of stainless steel is 0.002 mm.Determine the following:A)The pressure drop in _______ kPa.B)The head loss in _______ m.C)The pumping power requirement in _______ kW.
The required water flow rate in the 6 cm diameter 30-meter long circular pipe in the diagram below is 12 liters per second. The water temperature is 4 °C and the flow discharges into the atmosphere at a pressure of PB = 100 kPa. The flow is fully developed turbulent flow and there is no elevation change. The surface of the wall has become degraded due to pitting and deposits such that there is a surface roughness with a height...
