2 cards from this section. Quick, good the night before a test.
Define average velocity in the context of fluid flow.
Think about how average speed is measured.
What is the formula for calculating discharge?
Recall how to find the area of a circle.
What is the Reynolds number significance?
Consider what we discussed about flow types.
True or False: Average velocity increases with an increase in fluid viscosity.
Think about friction and its effect.
Calculate the discharge for a fluid flowing at a velocity of 2 m/s through a 10 cm diameter pipe, and determine if the flow is laminar.
Don't forget to convert diameter to meters!
For a fluid with density 1000 kg/m³ and dynamic viscosity 0.001 Pa.s, determine flow types and characteristics if the average velocity is 3 m/s and diameter is 0.1 m.
Focus on viscosity and its role in determining flow type.
