Question

For a fluid in a steady flow, the increase in flow speed at a constriction follows _____ (conservation of mass / Bernoulli's principle). Fill in the blank.

Answer 1

Answer:

For a fluid in a steady flow, the increase in flow speed at a constriction follows  conservation of mass while the decrease in pressure there follows from Bernoulli's principle.

Answer 2

Answer:

Explanation:

For a fluid in a steady flow, the increase in flow speed at a constriction follows conservation of mass .

Energy conservation is the foundation of Bernoulli's principle. According to this, the total amount of mechanical energy in a fluid travelling along a streamline is the same at every location along that streamline in a constant flow. This necessitates that the total amount of kinetic and potential energy stay constant.

What is Bernoulli's principle?

According to Bernoulli's principle, the total mechanical energy of a moving fluid, which includes the kinetic energy of the fluid's motion as well as the gravitational potential energy of elevation and pressure, remains constant.
