24.1.4. Types of Pressures

Try these first

1. 1.

   What is static pressure?

   Hint

   Think of a fluid that is not moving.

2. 2.

   Define dynamic pressure.

   Hint

   Consider how velocity affects pressure.

3. 3.

   What does static pressure measure?

   • Kinetic Energy
   • Potential Energy
   • Total Energy

   Hint

   Think about what it means when a fluid is not moving.

4. 4.

   True or False: Stagnation pressure combines static pressure and dynamic pressure.

   • True
   • False

   Hint

   Recall the definitions of both pressures.

5. 5.

   If a pipe system has a static pressure of 50 kPa and fluid flowing through it has a dynamic pressure of 20 kPa, calculate the stagnation pressure.

   Hint

   Use the relationship between static and dynamic pressure.

6. 6.

   What could be the implications in a design if dynamic pressure is significantly ignored in a hydraulic system?

   Hint

   Think about how fluid dynamics influences design safety.
