3 cards from this section. Quick, good the night before a test.
What are the components of a stress tensor?
Think about the definition of stress in fluids.
Define gauge pressure.
What happens to atmospheric pressure when we measure gauge pressure?
How many components are in a stress tensor?
Think about the arrangement of stress components.
True or False: Atmospheric pressure should always be included in calculations for fluid dynamics.
What happens to pressures acting uniformly?
A cylindrical tank has a height of 10 meters and radius of 2 meters. If the fluid inside has a density of 1000 kg/m³, calculate the gauge pressure at the bottom and the force acting on the bottom surface.
Use the formula for pressure and the formula for area of a circle.
A flow system has varying velocities across its cross-section. How do you calculate the total momentum using correction factors? Assume areas and average velocities for each section.
Consider the defined regions and apply the correction factors appropriately.
