2 cards from this section. Quick, good the night before a test.
What is the continuity equation for incompressible fluid?
Think about how mass is conserved in a fluid flow.
Define a stagnation point.
Consider where flow stops in relation to obstacles.
What does the continuity equation ensure in fluid dynamics?
Think about how fluids behave in a closed system.
True or False: Stagnation points occur when fluid velocity is zero.
Consider where the flow meets a solid surface.
In a given pipe network, the flows are A1=30 m³/s, A2=20 m³/s, and A3=Unknown. Compute the unknown flow rate at junction B.
Apply the mass conservation principle and remember that inflows can equate outflows.
Given a system with varying fluid densities, how would this impact the continuity equation? Explain and derive a modified equation.
Consider how density changes can occur under varying pressures.
