Pressure gradient is the rate of change of pressure over a certain distance. It describes how quickly the pressure changes as you move along a particular direction in a fluid medium.

Common units of measurement related to pressure gradient include Pascals per meter (Pa/m), pounds per square inch per foot (psi/ft), and millibars per kilometer (mb/km).

• It is crucial in fluid dynamics for understanding fluid flow behavior
• Helps in predicting the direction and speed of fluid movement in various systems
• Important in meteorology for analyzing weather patterns and predicting storms
