Water, with density of 1000 kg/m3 and kinematic viscosity of 1.0 x 10- m2/s, is pumped through a ...
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...
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)...
2. An oil having density of 833 kg/m3 and a viscosity of 3.3 x 103 Pa.s is pumped from an open tank to a pressurized tank held at 345 k Pa gauge. The oil is pumped from an inlet at the side of the open tank through a line of commercial steel pipe having an inside diameter of 0.07792 m at the rate of 3.494 x 103 m'/s. The length of the straight pipe is 122 m and the pipe...
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...
Water (density = 1000 kg/m3, viscosity = 1.15 x 10-3 N-s/m2) is delivered from a large reservoir upstream (Section"1") through two mortar lined steel circular pipes arranged in series to another large reservoir downstream (Section "2") as shown in Figure E4.7 The upstream pipe is 80 m long and 0.15 m in diameter, whereas the downstream pipe is 50 m long and 0.1 m in diameter. Both pipes have sharp-edged entrance and exit. Consider both major and minor losses. Determine...
2. Water flows at a rate of 60 L/s from a main reservoir to a subsidiary through a 600 m long, 185 mm diameter asphalted cast iron pipe as shown in the figure. The pipeline contains a gate valve, a globe valve and 4 standard 90° elbows.

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...
Water is to be withdrawn from a 3-m-high water reservoir by drilling a 1.5-cm- diameter hole in the center of the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole for a) a sharp edged entrance followed by threaded 90° bend and then a 3.5m length of wrought iron pipe and finally a fully open Globe Valve b) redo a) for the ideal case with no viscous losses
can you explain how can I solve this problem? Water at 60°F (15.6°C) (density 62.37 lb/ft3 and viscosity 1.129 cp) is to flow from reservoir A to reservoir B through a commercial steel pipe 6 in. in diameter as shown in Figure. The system contains sharped-edged entrance and exit, globe valve, and two standard 90° elbows. What should be the flow of water through the system? 00m Globe valve wide-open 500 m Sharp edged exit 100 m 100m Sharp-edge entrance
