A horizontal 150mm diameter pipe gradually reduces its section to 50mm diameter, subsequently, enlarging into 150mm section. The pressure in the 150-mm pipe at a point just before entering the reducing section is 140 kPa and in the 50mm section at the end of the reducer, the pressure is 70 kPa. If 600mm of head is lost between the points where the pressures are known, compute the rate of flow of water through the pipe.

6. A horizontal 150 mm diameter pipe gradually reduces its section to 50 mm diameter, subsequently enlarging into 150 mm section. The pressure in the 150 mm pipe at the point just before entering the reducing section is 140 kPa and in the 50 mm section at the end of the reducer the pressure is 70 kPa. If 600 mm of head is lost between the points where the pressures are known, compute the rate of flow of water thru the pipe.
2. A tank and piping system are shown below. The total length of PVC pipe is 2500 ft and discharges water into the atmosphere. The pipeline has an open globe valve and four threaded elbows; h1 = 10 ft and h2 = 45 ft." a. If the discharge is 0.5 cfs, what NPS should be used for the PVC pipe (ks = 0.00006 inch). b. What is the pressure at A, the midpoint of the pipeline? c. Draw the EGL and HGL. h2 Water T = 10°C (50°F) Globe valve

1.
A 60-inch main carrying 90 cfs branches at a point x into two pipes, one 1,000 ft. long 4 ft. in diameter and one 4,000 ft. long 2 ft. in diameter. Both pipes come together at a point y and continue as a single 60-inch pipe. Assuming the values of the friction factor f as 0.02, 0.022, and 0.024, respectively, for the 60-in., 48-in., and 24-in. pipes, compute the rate of flow in pipe 3 in cfs. Round your answers in 2 decimal places.
