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)

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
