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.

As a junior field engineer, you have been asked to assist a contractor in resolving the following problem. A 4.9 kW motor and gear drive rated at 175 rpm has been shipped with the four impeller blades listed below. The baffled rapid mix tank to which one of the impellers will be installed is 3.0 m² in volume (1.56 m diameter and 1.56 m depth). Assume water temperature of 10C, G= 1000s, water density = 1000 kg/m³, and motor power to water power transfer efficiency of 80%. Impeller options: A. Axial flow, 3 blades, diameter = 0.48 m, N₁-1.0 B. Axial flow, 3 blades, diameter = 0.61 m, Np=1.0 C. Radial flow, 6 blades, diameter = 0.48 m, Np=6.3 D.
