23.2.4. Significant Effects near Solids

Try these first

1. 1.

   What is the main principle underlying Bernoulli's equation?

   Hint

   Think about different forms of energy that fluids possess.

2. 2.

   List one assumption made when applying Bernoulli's equation.

   Hint

   Consider the properties of the fluid in motion.

3. 3.

   What principle does Bernoulli's equation represent?

   • Conservation of mass
   • Conservation of energy
   • Conservation of momentum

   Hint

   Recall the types of energy present in systems.

4. 4.

   True or False: Bernoulli's equation can be applied in the presence of significant friction.

   • True
   • False

   Hint

   Think about what friction does to energy.

5. 5.

   Consider a horizontal pipe where the diameter decreases, causing an increase in fluid speed. How is Bernoulli’s equation applied to find pressure variation?

   Hint

   Think about how velocity and pressure are inversely related.

6. 6.

   Evaluate how the introduction of a pump in a flow system affects the application of Bernoulli's equation.

   Hint

   Consider external energy inputs as part of total energy changes.
