Question 1.
What does the continuity equation represent?
Show hintHide hint
Think about mass flow rates.
Question 2.
In an incompressible flow, what happens to the density of the fluid?
Show hintHide hint
Consider the definition of incompressible flow.
3Question 3.
What does the equation of continuity relate to in fluid mechanics?
- Momentum conservation
- Energy conservation
- Mass conservation
Show hintHide hint
Remember the role of mass in fluid systems.
4Question 4.
In an incompressible flow, the density of a fluid is assumed to be constant.
- True
- False
Show hintHide hint
Think about how incompressible means constant.
Question 5.
A cylindrical tank with a radius of 2m has water flowing into it at a velocity of 3m/s. Calculate the volume flow rate and discuss how changes in tank area affect flow velocity.
Show hintHide hint
Consider the tank’s cross-sectional area and how it relates to flow rate.
Question 6.
Derive how the equation for an expanding nozzle fits within the principle of continuity, explaining the relationship between cross-sectional area and flow speed.
Show hintHide hint
Reflect on the conservation principle and how changes manifest physically.
