Question 1.
What happens to the pressure when fluid enters a pipe?
Show hintHide hint
Consider the forces acting on the fluid.
Question 2.
Define fully developed flow.
Show hintHide hint
Think about stability in flow conditions.
3Question 3.
What defines the entrance pressure drop?
- Pressure increase
- Immediate pressure drop
- Constant pressure
Show hintHide hint
Think about what happens to the fluid at the start of its journey.
4Question 4.
Is fully developed flow independent of pipe length?
- True
- False
Show hintHide hint
Consider the relationship between pipe length and flow stability.
Question 5.
A pipe with a diameter of 0.5 meters carries water at a Reynolds number of 3000. Determine the entrance length.
Show hintHide hint
Apply the formula specific to laminar flow conditions.
Question 6.
If a section of pipeline is known to be only 50 meters long, can it be assumed that the flow is fully developed at a flow rate of 1 m/s?
Show hintHide hint
Compare the given pipe length to calculated entrance length.
