2 cards from this section. Quick, good the night before a test.
Define laminar and turbulent flow.
Think about how syrup flows compared to water when poured quickly.
What is the Reynolds number threshold for laminar flow?
What happens when the numbers are too high?
What is the maximum Reynolds number for laminar flow?
Think of how fluid behaves smoothly.
Turbulent flow is characterized by:
Consider how fluid might mix or whirl.
A water supply system shows a pressure difference of 30 Pa over a 10 m length of pipe with a diameter of 0.5 m. Calculate the expected energy loss and identify if this suggests laminar or turbulent flow.
Use the pressure and length given to compute the energy loss!
Design a piping system in a home with multiple bends and valves. Estimate how minor losses will affect the overall efficiency and suggest improvements.
Focus on how reductions in number of fittings could improve performance!
