24.1.2. Applications of Bernoulli Equation

Try these first

1. 1.

   Define static pressure.

   Hint

   Think about how pressure would feel if you're underwater.

2. 2.

   What does a venturi meter do?

   Hint

   Recall how it narrows flow to calculate pressure changes.

3. 3.

   What is the primary role of the Bernoulli Equation in fluid mechanics?

   • Calculating temperature
   • Simplifying fluid flow problems
   • Measuring mass

   Hint

   Remember its applications in engineering.

4. 4.

   True or False: Dynamic pressure is a measure of a fluid's potential energy.

   • True
   • False

   Hint

   Consider what happens to fluid at rest.

5. 5.

   You have a pipe where water flows, experiencing a drop in pressure from 150 kPa to 120 kPa over a 10 meter stretch at a constant elevation. Calculate the flow velocity assuming incompressibility.

   Hint

   You need to express the change in kinetic energy.

6. 6.

   An aircraft measures airflow using a pitot tube. The static pressure recorded is 101.3 kPa while dynamic pressure is 20.7 kPa. Calculate the stagnation pressure.

   Hint

   Don't forget to sum both pressure types to find stagnation.
