24.6.2. Hydraulic Gradient Line

Try these first

1. 1.

   What is the hydraulic gradient line?

   Hint

   Think about energy components involved in a fluid system.

2. 2.

   Define static pressure.

   Hint

   What pressure do you measure without fluid movement?

3. 3.

   What does HGL stand for in fluid mechanics?

   • Hydraulic Gage Level
   • Hydraulic Gradient Line
   • Hydraulic Gain Level

   Hint

   Focus on what it describes regarding energy.

4. 4.

   True or False: Dynamic pressure is irrelevant in fluid mechanics.

   • True
   • False

   Hint

   Consider the implications of fluid motion.

5. 5.

   If a pipe has a pressure head of 10 m and an elevation head of 5 m, calculate the HGL.

   Hint

   Just add the respective components.

6. 6.

   In an experiment, fluid discharges through an orifice meter with a coefficient of discharge (Cd) of 0.85. If the theoretical discharge is 100 L/s, what is the actual discharge?

   Hint

   Multiply the theoretical discharge by the coefficient.
