24.6.1. Energy Gradient Line

Try these first

1. 1.

   What represents the total energy of a fluid system along a streamline?

   Hint

   Think about the components of energy in fluid flow.

2. 2.

   What kind of pressure does a manometer measure?

   Hint

   Consider the pressure that is present when the fluid is not in motion.

3. 3.

   What does the Energy Gradient Line represent?

   • Pressure only
   • Total energy of the fluid
   • Dynamic pressure only

   Hint

   Consider all components of fluid energy.

4. 4.

   Is dynamic pressure part of the Energy Gradient Line?

   • True
   • False

   Hint

   Think about the different forms of energy in the Energy Gradient Line.

5. 5.

   Given a vertical pipe where water flows with a height of 10 m and static pressure of 25,000 Pa, calculate the total energy at the base of the pipe if the water density is 1,000 kg/m³.

   Hint

   Apply Bernoulli's principles and remember units conversion.

6. 6.

   In a turbulent flow scenario, if the average velocity is 8 m/s, what kinetic energy correction factor should you apply if given that turbulent flow has α varying from 1.04 to 1.1?

   Hint

   Understand the reasons for adopting the average of the range.
