In the spherical coordinate …
WebWater containing 50 mg/L of monodisperse (uniformly sized) spherical particles of diameter 100 μm flows at a rate of 25 m3/h into a cylindrical tank with a depth of 5 m and a volume of 50 m3. The density of each particle is 2.5 g/cm3. The water temperature is 20 C (density = 1.0 g/cm3, viscosity = 0.01 g/cm-s). The only removal. Question ... WebA cylindrical lens is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to intersection of the surface of the lens and a plane tangent to it along the cylinder's axis.
