Along a level Bernoulli streamline, what accompanies a higher fluid speed?

Higher speed accompanies lower static pressure.

  1. Higher static pressure
  2. Lower static pressure ✔
  3. Unchanged static pressure always

Why: At constant height, p + one-half rho v squared remains constant for ideal flow. More kinetic energy density therefore corresponds to less pressure energy density.

Huh, didn't know that: Bernoulli's equation also includes gravitational potential energy density, rho g h, when height changes.

The dad joke
Bernoulli hurried through the pipe because he was under less pressure.
