There is a leak in a horizontal 30 cm pipeline (f= 0.025). Upstream from the leak two gages 600 m apart on the line show a pressures difference of 140 kPa. Downstream from the leak two gages 600 m apart show a pressure difference of 126 kPa. How much water is being lost from the pipe? a. 5 L/s b. 11 L/s c. 7 L/s d. 9 L/s

Question 1. Water flows with a discharge of 0,020 through a SG pipe reducer as is shown in the Figure 1. The static pressures at 1st (Di=0,31 m) and 2nd (D2=0,18 m)cross-sections are measured by the inverted U- D2 tube manometer containing oil of specific gravity, SG as 0,7. Determine the manometer reading, h *(m). (1) Water Figure 1

the marked answers are correct. Expalin the steps

The diameter of a pipe changes gradually from 6 inches at A to 18 inches at B. A is 15 ft lower than B. If the pressure at A is 10 lbs per square inch and at B, 7 lbs per square inch when there are 5.0 cubic ft per second flowing, determine: a. the direction of flow. b. the frictional loss between the two points B. If in Problem 1 the direction of flow is reversed, determine the pressure at A if all other factors, including the frictional loss, remain the same. C. In Problem 1, determine the diameter of pipe at B in order that the pressure at that point will also be 10 lbs per square inch, all other factors remaining constant. D. Determine the discharge in Problem 1, assuming no frictional loss, all other conditions remaining as stated. E. What would be the difference in pressure in pounds per square inch between A and B, Problem 1, if there were 6.2 cubic ft per second flowing, neglecting friction.

What is pipe roughness? A pump is located 5 m above the surface = 8170 M/m¹) in a closed tank. The pressure in the space above liquid surface is 35 Kpa. The suction line to the pump is 15 m of 15 cm diameter pipe (/= 0.025). The discharge from the pump is 60 m of 20 cm diameter pipe (/= 0.03). The pipe discharges in a submerged fashion to an open tank whose free liquid surface is 3 m lower than the liquid surface in the pressure tank. If pump puts 1.5 kW Into the liquid, determine the flow rate and the pressure in the pipe on the suction side of the pump. Assume turbulent flow.
