70% of the planet we live on is water. Seas, oceans, lakes, and rivers that flow constitute this 70%. This watering pattern caught the attention of the mathematicians who wished to predict and study the flow. This prediction became possible at the beginning of the 19th century all thanks to the Navier-stokes equation. This equation has aided the modern transport significantly. The most prominent mode of transportation that benefitted are ships. In addition, it also benefitted the cars and aircraft as air is the common fluid used for flights and aerodynamic principles aid in designs for cars.

For instance, to minimize the aerodynamic resistance in order to consume fuel efficiently, Navier-stokes is so precise that the engineers make use of the computer solutions that are based on equation rather than performing the physical trails in the wind tunnels.

This equation is broadly used in the medical research. It helps in calculating the flow of blood in the human body, facilitating surgeries like coronary bypass, which needs control of flow during the procedure.

Moreover, it even has applicability in the climate models. The two important aspects of climate are oceans and the atmosphere, both of these are fluids. Thus, this equation is used to investigate the matters of climate alterations.
