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)...
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...
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...
Water is to be withdrawn from a 3-m-high water reservoir by drilling a 1.5-cm- diameter hole in the center of the bottom surface.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
Problem 5: The system in the Figure consists of 1200 m of 5 cm cast-iron pipe, two 45o and four 90 flanged long-radius elbows, a fully open flanged globe valve, and a sharp exit into a reservoir.

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.

3) The system in Figure below consists of 1200 m of 5 cm cast-iron pipe, two 45° and four 90° flanged long-radius elbows, a fully open flanged globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m3/s of water at 20°C into the reservoir? (For water at 20°C, take p-998 kg/m3 and u-0.001 kg/m-s. For cast iron, take ε 0.26...
Please solve a,b,c,d,e,f 1) A water fountain is to be installed at a remote location by attaching a cast iron pipe directly to a water main through which water is flowing. The entrance to the pipe is sharp-edged 15m (K-0.5), and the 15m long piping system involves three 90 bends without vanes (K1.1), a fully open gate valve (K.-0.2), and a fully open angle valve (K-5). If the diameter of the pipe is 2 em and the system is to...
The system shown in the diagram consists of 1200m of cast-iron pipe with an internal diameter of 5cm (roughness of 0.00015 ft), two 45o and four 90o long radius elbows, a fully open bevel seat globe valve, and a sharp exit into a reservoir. If the elevation difference between the inlet and level in the reservoir is 10m, what gauge pressure is required at point 1 to deliver 0.005m^3/s of water at 20oC into the reservoir (use density of 998.2...
