22.4. Bernoulli Experiment

Try these first

1. 1.

   What happens to fluid velocity as the cross-sectional area of flow decreases?

   Hint

   Consider the continuity equation.

2. 2.

   Define the Bernoulli equation in simple terms.

   Hint

   Think of it as an energy balance equation.

3. 3.

   What is the primary application of Bernoulli's equation in fluid mechanics?

   • To measure fluid density
   • To analyze energy conservation
   • To determine viscosity

   Hint

   Think about what aspects of fluid flow it helps describe.

4. 4.

   True or False: Bernoulli's principle states that as the speed of fluid increases, the pressure decreases.

   • True
   • False

   Hint

   Recall the relationship between speed and pressure in fluid dynamics.

5. 5.

   A blood vessel narrows from 6 mm to 3 mm. If the initial velocity is 1 m/s, what is the new velocity of blood assuming incompressible flow?

   Hint

   Use the continuity equation for incompressible fluids.

6. 6.

   How would you calculate the pressure difference between two points in a venturimeter given the flow rate and diameter?

   Hint

   Think about changes in cross-sectional area.
