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.

A single-stage axial flow pump with outer radius r2 = 0.240 m and inner radius r1=0.120 m is given. At a radius of r =0.090 m, absolute flow flows in from the axial direction just before the impeller inlet and relative flow flows out in the axial direction just after the impeller outlet. Assuming a flow rate Q = 0.265 m^3/s, a water density p = 1.000 x 103 kg/m^3, a rotation speed n = 2.4 x 10^3 rpm, and a gravitational acceleration g = 9.81 m/s^2, and assuming that the theoretical head Hth = W/g (W: specific work) derived from Euler's law is constant at all impeller radii, answer the following questions.
