Question 1.
Define Poiseuille's Law and its basic formula.
Show hintHide hint
Consider what each term represents.
Question 2.
What does a higher viscosity imply about fluid flow?
Show hintHide hint
Think about how honey flows compared to water.
3Question 3.
What is Poiseuille's Law primarily used for?
- Predicting laminar flow
- Calculating turbulent flow
- Analyzing gas flow
Show hintHide hint
Think about what kind of fluid flow is addressed by the equation.
4Question 4.
When gravity is included in pipe calculations, which term is added?
Show hintHide hint
Consider the angle of slope when recalling this term.
Question 5.
A 10 m long, 0.04 m diameter pipe is inclined at 15°. Compute the pressure drop for water flowing through it at a velocity of 1 m/s with a viscosity of 0.001 Ns/m².
Show hintHide hint
Use both aspects: viscous resistance and gravitational effect.
Question 6.
If we elevate a pipe and modify its angle, causing a flow rate of zero, discuss the implications for pressure at start and end points.
Show hintHide hint
Reflect on the balance of pressures between two points with no flow.
