4 cards from this section. Quick, good the night before a test.
What is the momentum flux correction factor in laminar flow?
Think about the ratio of averaged to actual velocities.
Define laminar flow.
Consider how different layers interact.
What is the typical beta value for laminar flow?
Consider average velocities compared to actual distributions.
True or False: Turbulent flow has a beta value close to 1.
Think about how velocity flows in turbulent vs laminar scenarios.
A sluice gate at a depth of 10m experiences a flow velocity of 4m/s. Calculate the horizontal force on the gate if the density of water is 1000 kg/m³.
Focus on hydrostatic pressure for calculations.
A horizontal water jet with a diameter of 10mm flows into a plate, creating a force. Given velocity at 5m/s, find the force with ρ = 1000 kg/m³.
Use continuity principles to relate jet area to velocity.
