Interpret Bernoulli's equation: When elevation, h, and flow velocity, v, are both reduced, what happens to the pressure, P?
Homework Answers
Bernoulli's equation states that in a fluid flow, the sum of the pressure, potential energy per unit volume, and kinetic energy per unit volume is constant at any point along the flow. In other words, if the elevation and flow velocity of a fluid are both reduced, the pressure will increase to maintain the constant sum of the three energy terms. This is known as the Bernoulli principle, and it explains phenomena such as lift in airplane wings and the flow of fluids through narrow channels.
