A centrifugal pump of the following characteristics is used to pump the water between 2 reservoirs, over a distance of 0.1 km. The pipe is 10 cm in diameter and is constructed from slightly rusted steel with material roughness of 0.3 mm. Coefficients of minor loses through the system equates to 10. If the difference in elevation between the reservoirs is 20 m, on the assumption of fully turbulent flow: a) Draw an accurate diagram of the system and annotate datum level, b) State main assumptions and simplify the Bernoulli's equation accordingly c) An expression for the actual system requirement in terms of fluid velocity, d) Characteristic pump pressure in terms of velocity, from , e) Operating point of the system- compatible volumetric flow rate, n Confirm the fully turbulent flow assumption.
Theory and Design for Mechanical Measurements
Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.
Basic principles of engineering metrology
Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.
