3 cards from this section. Quick, good the night before a test.
What is Poiseuille's Law used for?
Think about the relationship between pressure and flow in the system.
Define Reynolds number.
Remember, it distinguishes between laminar and turbulent flow.
What is the primary purpose of Poiseuille’s Law?
Focus on what the law fundamentally relates.
True or False: Reynolds number above 2100 indicates laminar flow.
Remember the significance of the critical threshold.
Determine the angle necessary for an inclined pipe to maintain a flow rate of 0.05 m³/s if the pressure drop is zero. Assume water with a viscosity of 0.001 Pa.s and density of 1000 kg/m³.
Your formula will involve gravitational acceleration and require manipulating the pressures involved.
A 50 m long pipe with a diameter of 0.05 m has water flowing through it at a velocity of 2 m/s. Calculate the pressure drop, and confirm if the flow is laminar or turbulent.
Look for the viscosity of water at standard conditions.
