Question 1.
What is head loss in pipes?
Show hintHide hint
Think about what happens to energy when fluid moves through a pipe.
Question 2.
Define laminar flow.
Show hintHide hint
Consider how the layers of fluid move in relation to each other.
3Question 3.
What is head loss in fluid mechanics?
- Energy loss from fluid
- Increase in pressure
- Magnitude of fluid speed
Show hintHide hint
Think about the effects of friction.
4Question 4.
True or False: Reynolds number above 4000 definitively indicates laminar flow.
- True
- False
Show hintHide hint
What happens at the transition threshold?
Question 5.
A fluid flows through a 0.1 m diameter pipe at 1.5 m/s with a viscosity of 0.002 Pa·s. Is the flow laminar or turbulent? Calculate the Reynolds number.
Show hintHide hint
Remember the factors in the Reynolds number.
Question 6.
Design a piping system for a building that minimizes head loss while ensuring adequate pressure. Consider flow rates and pipe diameter.
Show hintHide hint
How does pipe diameter affect friction?
