Question 1.
Define pressure drop in pipe flow.
Show hintHide hint
Think about what happens to pressure when fluid moves through a surface.
Question 2.
What is laminar flow?
Show hintHide hint
Consider how fluid behaves at low velocities.
3Question 3.
What is the formula to calculate the entrance pressure drop in laminar flow?
- 0.06 Re
- Re^1/6
- 0.04 Re
Show hintHide hint
Recall the specific formula discussed for laminar flow.
4Question 4.
In fully developed flow, the pressure drop per unit length is:
- True
- False
Show hintHide hint
Think about what it means for flow to be fully developed.
Question 5.
A cylindrical pipe of length 20 m and diameter 0.1 m has a pressure drop of 500 Pa. Calculate the flow rate if the viscosity of the fluid is 0.001 Pa.s.
Show hintHide hint
Remember to correctly apply the formula and double-check unit conversions.
Question 6.
Explain how varying fluid viscosity would affect flow rates in real-life piping systems.
Show hintHide hint
Think about how different fluids behave in your daily experiences, like water versus honey.
