6 sample questions

Question 1.
What is the entrance pressure drop formula for laminar flow?
Show hintHide hint
Think about how the flow regime affects the formula.
Question 2.
Define shear stress in simple terms.
Show hintHide hint
Consider what happens when layers slide past each other.
3Question 3.
What is the entrance pressure drop for laminar flows?
- Re^(1/6)
- 0.06Re
- 1.5Re
Show hintHide hint
Recall the distinction between laminar and turbulent calculations.
4Question 4.
Is the pressure drop per unit length constant in fully developed flow?
- True
- False
Show hintHide hint
Think about the nature of acceleration in different flow conditions.
Question 5.
Design a pipe system where you want to ensure fully developed laminar flow. Discuss dimensions and flow rates based on given material characteristics.
Show hintHide hint
Use laminar flow formulas to ensure your design meets criteria.
Question 6.
Consider a scenario where a fluid is flowing in a long horizontal pipe of constant diameter. If the fluid changes temperature, affecting viscosity, how would this impact pressure drop and shear stress?
Show hintHide hint
Link viscosity changes to friction and pressure equations.
