2 cards from this section. Quick, good the night before a test.
What is the condition for flow to be considered laminar?
Recall the threshold for laminar flow.
If the viscosity of a fluid is given as 0.5 poise, what is its value in SI units?
Remember the conversion factor to SI units.
What is the key factor deciding whether flow is laminar?
Think about the number that defines flow behavior.
In laminar flow, shear stress is proportional to:
Consider how shear stress behaves relative to velocity in a fluid.
A liquid with a viscosity of 0.8 Pa·s flows through a pipe of diameter 30 mm at an average velocity of 1.5 m/s. Calculate the Reynolds number and determine if the flow is laminar or turbulent.
What is the density assumption based on specific gravity?
Identify the pressure difference required for maintaining a constant flow rate of 0.005 m³/s in a horizontally placed pipe of 40 mm diameter having a length of 50 m and a viscosity of 0.1 Pa·s.
Focus on understanding the effect of radius and viscosity on flow.
