24.1.6. Fluid Flow Problems Related to Bernoulli Equations

Try these first

1. 1.

   What does Bernoulli's equation relate in fluid dynamics?

   Hint

   Think about the main elements affecting fluid flow.

2. 2.

   What is static pressure?

   Hint

   Consider the pressure when fluid is not flowing.

3. 3.

   What does Bernoulli's equation primarily describe?

   • Relationship between temperature and pressure
   • Relationship between pressure
   • velocity
   • and height
   • Relationship between mass and volume

   Hint

   Think about the main ideas of fluid movement.

4. 4.

   Is dynamic pressure zero when fluid is at rest?

   • True
   • False

   Hint

   Consider what happens to fluid motion.

5. 5.

   A fluid with a density of 800 kg/m^3 is flowing through a pipe with varying diameter. The diameter at point A is 0.5 m and at point B is 0.25 m. If the velocity at point A is 12 m/s, calculate the velocity at point B using the continuity equation.

   Hint

   Remember to convert diameter to radius for area calculations.

6. 6.

   An orifice meter shows a pressure difference of 2000 Pa for a discharge of 0.01 m^3/s. Calculate the coefficient of discharge if the area of the orifice is 0.001 m^2.

   Hint

   Make sure to substitute values correctly.
