Water (density 998 kg/mº, dynamic viscosity 0.001 Pa s) is pumped between two reservoirs at a volumetric flow rate of 0.006 m/s through a 120-m long pipe of 5 cm diameter. The roughness ratio of the pipe is a/d = 0.001. There are some fittings and valves in the pipe system, as shown in Figure Q1. The loss coefficients of the valves and fittings can be found in Table Q1. The Darcy friction factor can be found in the Moody...
(b) Water flows under gravity between two reservoirs through a pipe of length 5000m. The diameter of the pipe is 0.2 m and the roughness size is 0.04 mm. The water levels in the two reservoirs are maintained with a difference of 50 m. Determine the discharge through the pipe. Neglect all minor losses. Use the attached Moody diagram for estimation of friction factor. (10 marks) (c) In (b), now include entry loss at the upper reservoir with loss coefficient...
Oil (density = 910Kg/m3 and viscosity 3.1 x10-3 Pa-s) is pumped from an open tank to a pressurized tank held at 400KPa gauge. The oil is pumped from an inlet at the side of the open tank through a line of commercial steel pipe (inside diameter 0.8m) at a rate of 5x10-3 m3/s. The length of the straight pipe is 150 m, and the pipe contains 4 (90-degree) elbows and two globe valve half open. The level of the liquid...
Task 1: You were asked to check up the status of the water system. Water at 24 °C is to be pumped from a Lower reservoir with 100 m elevation to another reservoir at a higher elevation 112 m through 150-m-long pipe as shown in Figure (1). The pipe is made of steel, and the diameter of the pipe is equal to 30 cm. Water is to be pumped by a 72% efficient motor-pump combination that draws 33 A of...
Water is being pumped from reservoir A to reservoir F through a 30-m long PVC pipe (e 0) of diameter 0.150 m. There is an open gate valve located at C; 90 bends (threaded) located at B. D and E; and a pump shown with the letter P. The pump is required to deliver 0.25 m'/s of water to reservoir F from A. NOTE: p. 1000 kg/m. y=9.80 kN/m, v= 1.12 x 10 m/s L-30-m to' -0.25m %2 10 m...
Two water reservoirs A and B are connected to each other through a 35m-long, 2-cm-diameter cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve. The water level in both reservoirs is the same, but reservoir A is pressurized by compressed air while reservoir B is open to the atmosphere at 94 kPa. If the initial flow rate through the pipe is 1.2 L/s, determine the air pressure (gage)...
10. Problem 12.38 from the textbook (Statement: In a chemical processing plant a liquid is pumped from an open tank, through a 0.1-m-diameter vertical pipe, and into another open tank as shown in the figure (a). A valve is located in the pipe, and the minor loss coefficient for the valve as a function of the valve setting is shown in figure (b). The pump head capacity relationship is given by the equation ha =52.0-1.01x10?Q? with ha in meters when...
Question 5 a) As shown in Figure Q5 (a), crude oil at 60°C with ρ-860 kg/m3 and μ-3.91 x 10" kg s/m (about four times of viscosity of water) is pumped across from City A to City B pipeline, a 1286 m long, 1.22 m diameter steel pipe ( 0.0125), at a maximum rate of Q- 3.31 m'ls. Investigate the horsepower (unit in hp) needed for the pumps that drive this large system. (Neglect minor losses in the system) Oil:...
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...
Q3 (40 pts): Water is pumped through a 60-m-long, 0.3-m-diameter pipe from a lower reservoir to a higher reservoir, which has a water surface 10 m above the lower one. When the pump adds 40 kW to the water the flowrate is 0.20 m/s. Assume the following coefficients of minor losses: • Entrance: Kentrance = 0.5 Exit: Kexit = 1 Each elbow: Kelbow = 1.5 • Valve: K= 6 Part A (20 pts) Determine the pipe roughness ε. Part B...
