3 cards from this section. Quick, good the night before a test.
What is the continuity equation?
Think about what must happen to a fluid's mass as it moves through a pipe.
Define laminar flow.
Consider the nature of the layers in laminar flow.
What does the continuity equation express?
Think about conservation principles in fluid mechanics.
True or False: The Navier-Stokes equation is only applicable to turbulent flows.
Recall the broad applications of the equation.
A fluid with viscosity 0.5 N·s/m² and density 800 kg/m³ flows through a pipe with a diameter of 0.025 m at a flow rate of 3 x 10⁻⁵ m³/s. Calculate the pressure drop using Poiseuille's law.
Convert diameter to radius in calculations.
If the same fluid flows uphill in a pipe at an angle θ, how does gravity affect the flow rate?
Consider the vertical component of pressure due to gravity.
