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. 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?

Question in the picture smooth pipe: Total length, L Diameter, d -25 mm 4 m tank water (pa 1,000 kg/m3, μ 0.001 kg/ms) flows from a very large tank (that is open to atmosphere) through an L 4 m total length of smooth pipe of d = 25 mm diameter at a bulk velocity of 6 m/s. The water then exits the pipe at 3 m above ground as a free jet. The pipe network contains a gate valve (V),...
(100 points) Water at 25°C is pumped at a rate of 0.075m's from a reservoir 20m above a pump to a free 1. discharge (this means discharged to atmosphere) 35m above the pump. The pressure on the intake side of the pump is 150kPa and the pressure on the discharge side of the pump is 450kPa. The pipe between the reservoir and the pump is 3 meters of Sin diameter cast iron. From the pump to the discharge the pipe...
Threaded regular 90° elbow Square-edge exit Square-edge entrance Half-open gale valve Miter 90° elbow Open globe valve Water is pumped between two reservoirs through a 5 cm diameter pipe that is 12.2 m long with a number of minor losses shown in the image. The elevation difference between the two reservoirs is Az = 2.8 m. For a pipe roughness ratio of e/D=0.001, what is the minimum pump power (in W) required to move 30°C water at a volumetric flow...
A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2....
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...
Water flows from the upper tank to the lower tank through a cast iron pipe of total length L-1100 ft through one half-closed gate valve, four regular 90° flanged elbows, and entrance/exit as shown. For 2 cases with the same pipe perimeter P 12 in., compute the volume flow rate (ft /s) through: circular pipe of diameter D, and equilateral triangular pipe with each side a. a) b) Note that the flow areas and hydraulic diameters will be different. Find...
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)...
this is all of the information given Problem 3. A piping system consists of 1200 m of 5 cm diameter cast-iron pipe, two 45° and four 90° flanged long-radius elbows, a fully open flanged globe valve, and a sharp submerged exit into a reservoir. The elevation of the outlet relative to the inlet is 100 m. What gage pressure is required at the inlet to deliver 0.005 m2/s of water at 20°C into the reservoir? Assume that the density and...
