Pressure Changes Across Curved Streamlines

Bernoulli's equation for flow normal to a streamline describes how pressure changes across curved streamlines. When a fluid follows a curved path, the outer side of the curve experiences centrifugal force, which pushes the fluid outward. The pressure is therefore higher on the inner side, near the center of curvature, and lo...

Bernoulli's equation for flow normal to a streamline explains how pressure varies across curved streamlines due to outward centrifugal forces.

Pressure is higher on the inner side of the curve, near the center of curvature, and decreases outward to balance these centrifugal forces.

The pressure difference depends on the fluid's vel...
