How does a pressure gradient result in a force?

The pressure-gradient force is the force that results when there is a difference in pressure across a surface . In Earth's atmosphere, for example, air pressure decreases at altitudes above Earth's surface, thus providing a pressure-gradient force which counteracts the force of gravity on the atmosphere.

How do you calculate pressure gradient?

The easiest way to calculate pressure from depth is to use the pressure gradient of the given fluid. Pressure gradients for incompressible fluids have units of pressure/depth. For example, psi/ft, bar/m.

What is a strong pressure gradient?

Pressure gradient force is the force that moves air from an area of high pressure to an area of low pressure. The velocity of the wind depends upon the pressure gradient. If the pressure gradient is strong, the wind speed is high. If the pressure gradient is weak, the wind speed is light.
