The mass of a material substance per unit volume is called density. Density is calculated using the formula d = M/V, where d represents density, M is mass, and V is volume. The density of a substance is usually measured in grammes per cm³.

The concept of velocity for an object is the rate at which the object's position changes in relation to a frame of reference and time. It's a vector quantity, which means we need both magnitude (speed) and direction (orientation) to define velocity. Its SI unit is meter per second (m/s). When the amount or direction of a body's velocity changes, the body is said to be accelerating.

Characteristic length is a crucial dimension in physics that specifies the scale of a physical system. Characteristic length is defined in computational mechanics to force localization of a stress softening constitutive equation. An integration point is referred to the length.

The Reynolds number is a ratio that supports in the prediction of flow patterns in various fluid flow situations. Flows with high Reynolds numbers tend to be turbulent, and flows with low Reynolds numbers tend to be laminar. Because Reynolds number is a dimensionless parameter, there are no units for it. In other words, the Reynolds number is a quantity that is one unit less.
The flow of a fluid in parallel layers is referred to as laminar flow. Fluid flows in a laminar flow without being disrupted. Turbulent flow, on the other hand, refers to fluid that does not flow in parallel layers due to changes in velocity, pressure, and other factors. It flows across the tube in a layered pattern.
