Pressure Gradient

Pressure gradient refers to the change in pressure over a certain distance. It is a measure of how rapidly or slowly the pressure changes in a particular direction within a fluid or a gas.

In the context of fluid dynamics, pressure gradient is an important concept that helps us understand the flow of fluids and the forces acting within them. The pressure gradient is a key factor in determining the direction and speed of fluid flow.

A pressure gradient can be represented by the formula:

Pressure Gradient = Change in Pressure / Distance

Where the change in pressure is measured in units such as Pascals (Pa) or pounds per square inch (psi), and the distance is typically measured in meters or feet.

Pressure gradients play a significant role in phenomena such as wind patterns, ocean currents, and the flow of blood within the human body. Understanding pressure gradients is crucial in fields such as meteorology, oceanography, and medical science.
