A pump is required to move water at a design discharge of 1m3 /s between reservoir A to reservoir B (see schematic below). The difference in surface water elevations between A and B is 10m. The difference in elevation between the surface elevation of A and the center of the first pipe section is 2m. The pipe is to be commercial steel with an internal diameter of 35cm. Determine the maximum distance, LAP, from reservoir A that the pump could be installed without encountering cavitation problems. Consider minor losses of a sharp-edged inlet. Assume a kinematic viscosity of 1x10-6 m 2 /s and a specific weight of 9.79kN/m3 . Assume STP conditions (i.e., Pvapor = 3kPa, Patm=101.3kPa)

Question

A pump is required to move water at a design discharge of 1m3 /s between reservoir
A to reservoir B (see schematic below). The difference in surface water elevations between A and B is
10m. The difference in elevation between the surface elevation of A and the center of the first pipe section
is 2m. The pipe is to be commercial steel with an internal diameter of 35cm. Determine the maximum
distance, LAP, from reservoir A that the pump could be installed without encountering cavitation
problems. Consider minor losses of a sharp-edged inlet. Assume a kinematic viscosity of 1x10-6 m 2
/s and a specific weight of 9.79kN/m3 . Assume STP conditions (i.e., Pvapor = 3kPa, Patm=101.3kPa)

A 10m 2m LAP=? P₁ B
Transcribed Image Text:A 10m 2m LAP=? P₁ B
