1. Introduction
Laminar & Turbulent Flow
A laminar flow refers to a flow in which a layer moves in a traveling direction because fluid particles are attached to each other and thus do not diffuse well. Turbulence refers to a disorderly and unsteady-State flow, as opposed to laminar flow, has low diffusion, high momentum convection, and changes rapidly over time.

Reynolds number
The Reynolds number is the ratio of force due to inertia to force due to viscosity, indicating the relative dynamics of these two types of forces under a given flow condition. Reynolds number is one of the most important dimensionless numbers in hydrodynamics, and this Reynolds number can be used to determine whether the fluid flow is laminar or turbulent. In general, laminar flow is defined as when the Reynolds number is lower than 2100 and when the Reynolds number is higher than 4000.

Continuity Equation
The continuous equation is a mathematical representation of the law of mass conservation.
