A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree.

This system utilizes a Computer Tomography or CT unit and an (MRI) Magnetic Resonance Imaging unit to obtain a detailed view of a body. Here the MRI images and the detailed X-rays are combined to create a full three-dimensional …
The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase. The effect is mathematically described through the Bernoulli equation and can be observed in both nature and industry. Many industry applications rely on …
