Flow Velocity

Flow velocity in fluids is the vector field that provides the velocity of fluids at a certain time and position. The entire length of the flow velocity is referred to as the flow speed.

Flow velocity is also known as macroscopic velocity.

The flow velocity of fluids efficiently defines everything about the fluid's motion. A lot of fluids' physical properties can be expressed in a mathematical manner. Proper measurement and monitoring of flow velocity can help in many ways, including the prevention of corrosion.

For instance, cavitation is at times regarded as a special type of corrosion-erosion. This is caused by the collapse and formation of vapor bubbles within a liquid close to a metal surface. The succeeding corrosion attack is the product of hydro-mechanical processes from fluids in areas with low pressure wherein the flow velocity alters, disrupts or changes in terms of the flow of direction that took place.

Thus, industries, specifically those involved in offshore well systems, should perform careful selection of materials along with proper design to minimize damage. It is also recommended to encourage laminar flow and decrease fluid velocity along with increasing the diameter of pipes to effectively prevent and control corrosion damage.
