4 cards from this section. Quick, good the night before a test.
Define static pressure.
Think about how pressure would feel if you're underwater.
What does a venturi meter do?
Recall how it narrows flow to calculate pressure changes.
What is the primary role of the Bernoulli Equation in fluid mechanics?
Remember its applications in engineering.
True or False: Dynamic pressure is a measure of a fluid's potential energy.
Consider what happens to fluid at rest.
You have a pipe where water flows, experiencing a drop in pressure from 150 kPa to 120 kPa over a 10 meter stretch at a constant elevation. Calculate the flow velocity assuming incompressibility.
You need to express the change in kinetic energy.
An aircraft measures airflow using a pitot tube. The static pressure recorded is 101.3 kPa while dynamic pressure is 20.7 kPa. Calculate the stagnation pressure.
Don't forget to sum both pressure types to find stagnation.
