A pipeline with roughness ks = 1.0mm and diameter D = 9.6cm connects two reservoirs. The reservoirs are both open to the atmosphere and differ in surface elevation by H = 40m. The two reservoirs with the connecting pipe are shown in the figure below. You can assume density of water = 1001kg/m³, dynamic viscosity of water = 0.001Pa-s and acceleration due to gravity 9.81 m/s². Local losses must be considered; assume reasonable values as introduced in the ENGG2500 lectures. Reservoir Pipe with D.K.

Metrology of surface finish

In general terms, the application of scientific principles in the study of measurements is known as metrology. When speaking about measurement, it could be of time, length, microstructures, grain structures, internal crystal discontinuities, surface roughness, measurements of angles, height, width, and so on. While coming to the domain of mechanical engineering, metrology is considered the science of measurements of surface finish, length, surface texture, and angles.
