2 cards from this section. Quick, good the night before a test.
What is the principle of mass conservation in fluid dynamics?
Think about balance in a system.
Define incompressible flow.
What happens to volume in such a flow?
Which theorem relates momentum change to flux across a control volume?
Consider the main theorems used in fluid dynamics.
True or False: Incompressible flow implies varying density.
Think about the definition of incompressible fluid.
A water jet strikes a vane at an angle with a velocity of 10 m/s and a cross-sectional area of 0.05 m². Evaluate the force on the vane when the flow is steady.
Factor in the direction of jet impact.
During a steady flow of oil in a pipeline, with a density of 800 kg/m³, the cross-section reduces from 0.1 m² to 0.05 m². Calculate the change in velocity if the input pressure is known.
Consider adding Bernoulli's equation where necessary.
