2 cards from this section. Quick, good the night before a test.
What is the formula for the Cauchy number?
Remember, it involves density and velocity.
What does the Cauchy number quantify?
Think about the type of forces at play in fluids.
What is the Cauchy number used to measure?
Consider the main two forces it relates.
True or False: Compressibility is irrelevant in most liquids.
Think about the common properties of liquids compared to gases.
Analyze the flow of a gas in a pipe where the fluid density is 2.5 kg/m³, the modulus of elasticity is 200 kPa, and the velocity of the gas is 15 m/s. Calculate the Cauchy number and discuss its significance in terms of compressibility considerations.
Use the formula and analyze the number you calculate.
Given different flow scenarios with the same fluid, discuss how variations in velocity and density would impact the Cauchy number. Provide examples of situations where one may be more relevant than the other.
Think about real-world applications in high-speed transport.
