Question 115

When kinetic energy goes down (like in the Bernoulli tube), does potential energy go up?
Yes. When a fluid that's in steady state flow (moving smoothly and continuously past stationary obstacles) loses kinetic energy, its potential energy goes up—either its pressure rises or it moves upward against gravity. That assumes that the kinetic energy isn't being lost to thermal energy because of some terrible friction problem.
