The Pressure Gradient Equation describes the change in pressure with respect to distance in a fluid flow field. It’s a fundamental equation in fluid mechanics and is commonly used to analyze the behavior of fluids in pipes, channels, and other conduits. Mathematically, the Pressure Gradient Equation can be expressed as:
Where:
- is the pressure gradient, representing the rate of change of pressure with respect to distance,
- is the density of the fluid,
- is the acceleration due to gravity.
