22.2. Introduction to Bernoulli's Equations

Try these first

1. 1.

   What is Bernoulli's equation used for?

   Hint

   Think about the conservation principles in fluid dynamics.

2. 2.

   Name one assumption when applying Bernoulli's equations.

   Hint

   Consider the behavior of fluids under different conditions.

3. 3.

   Bernoulli's principle states that as the velocity of a fluid increases, its pressure decreases.

   • True
   • False

   Hint

   Think about the relationship between kinetic energy and pressure.

4. 4.

   In which type of flow can Bernoulli's equation be applied?

   • Incompressible flow
   • Compressible flow
   • Both

   Hint

   Recall the assumptions for applying Bernoulli's principles.

5. 5.

   Calculate the pressure difference between two points in a horizontal pipe where fluid velocity at point A is 5 m/s and at point B is 10 m/s. Assume the fluid density is 1000 kg/m³.

   Hint

   Use the Bernoulli equation and focus on velocity differences.

6. 6.

   Discuss the implications of using Bernoulli's equation for non-steady flows and provide examples.

   Hint

   Think about flow characteristics and energy conservation.
