Question 1.
What is the principle of mass conservation?
Show hintHide hint
Think about inflow and outflow in a control volume.
Question 2.
Define incompressible flow.
Show hintHide hint
Consider what happens in liquids under normal conditions.
3Question 3.
What is mass conservation in fluid dynamics?
- Mass can be created
- Mass must be conserved
- Mass can be destroyed
Show hintHide hint
It's related to inflow and outflow.
4Question 4.
True or False: Incompressible flow means that the density of the fluid changes.
- True
- False
Show hintHide hint
Consider how liquids behave under pressure.
Question 5.
A horizontal jet strikes a vane angled at 30 degrees. If the flow rate is known, calculate the force required to hold the vane stationary.
Show hintHide hint
Use trigonometric functions for angle adjustments.
Question 6.
Assess the impact of increasing jet velocity on the forces calculated on a vane using prior knowledge.
Show hintHide hint
Consider how higher velocities influence the jet's energy.
