Answer to Question #262689 in Civil and Environmental Engineering for jane

Question

1.)  A 300-mm pipe carries oil of sp gr 0.812 at a rate of 0.111 m /s, and the pressure at a point A is 18.4 kPa gage. If point A is 1.89 m above the datum plane, calculate the energy at A.

2.) Water flows upward in a vertical 300-mm pipe at the rate of 0.222 m /s. At point A in the pipe the pressure is 210 kPa. At B, 4.57 m above A, the diameter is 600 mm, and the lost head A to B equals 1.83 m. Determine the pressure at B.

3.) A 12′′ pipe line carries oil of specific gravity 0.811 at a velocity of 80.0 ft/sec. At points A and B, measurements of pressure and elevation were 52.6 psi and 100.0 ft and 42.0 psi and 110.0 ft, respectively. For steady flow, find the lost head between A and B. 

4.) A reservoir supplies water to a horizontal 6′′ pipe 800 ft long. The pipe flows full and discharges into the atmosphere at the rate of 2.23 cfs. What is the pressure in psi midway in the pipe, assuming the only lost head is 6.20 ft in each 100 ft of length?
