Question 2 A centrifugal pump delivers 0.1 m³/s of water at a rotational speed of 1200 rev/min. The impeller has seven vanes which lean backwards to the direction of rotation such that the blade tip angle is 40°. The impeller has an external diameter of 0.4 m, an internal diameter of 0.2m and an axial width of 31.7 mm. Assuming that the diffuser efficiency is 51.5%, that the impeller head losses are 10% of the ideal head rise and that the diffuser exit is 0.15m in diameter, determine (a) The manometric head (b) The hydraulic efficiency

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
