Question 1.
What is the principle of conservation of mass?
Show hintHide hint
Think about how mass behaves when no external forces are acting.
Question 2.
Define viscosity in simple terms.
Show hintHide hint
Consider how honey flows compared to water.
3Question 3.
What does the law of conservation of energy state?

- It can be destroyed.
- It can only change forms.
Show hintHide hint
Think of energy in terms of transformations.
4Question 4.
In an incompressible fluid, what is the divergence of velocity equal to?
- True

Show hintHide hint
Remember the continuity equation!
Question 5.
Calculate how much energy is lost in a hydraulic system because of friction when a fluid circulates through a pipe. Given fluid properties and friction factors.
Show hintHide hint
Think about loss coefficients and friction equations.
Question 6.
If the temperature of a hydraulic fluid increases, discuss how you might expect its viscosity to change and the potential consequences.
Show hintHide hint
Relate viscosity changes to energy conservation in systems.
