Show hintHide hint
Think about liquids versus gases.
3Question 3.
What does the Continuity Equation represent?
- Mass creation
- Mass destruction
- Mass conservation
Show hintHide hint
Think about the principles of physics.
4Question 4.
In incompressible flow, what must the continuity equation equal?
- True
- False
Show hintHide hint
Focus on the idea of fluid density.
Question 5.
A water pipe has a diameter of 0.5 m and a velocity of 2 m/s. If the diameter of a downstream section of pipe is 0.25 m, what is the new velocity?
Show hintHide hint
Remember to convert diameter to radius before calculating area.
Question 6.
In an irrigation system, water flows from a wider channel of 5 m² area to a narrow nozzle of 1 m² area. If the flow velocity in the wide channel is 4 m/s, find the velocity at the nozzle.
