5 cards from this section. Quick, good the night before a test.
What is the momentum flux correction factor for laminar flow?
Think about how the velocity distribution looks in laminar flow.
Explain hydrostatic pressure.
Consider how pressure changes with depth.
What is the value of the momentum flux correction factor for laminar flow?
Reflect on the characteristics of laminar flow.
True or False: In turbulent flow, the momentum flux correction factor is usually around 1.
Think about how velocity behaves in turbulent versus laminar scenarios.
Derive the expression for the horizontal force acting on a sluice gate if h1 is 5m, h2 is 2m, and the velocity at the inlet is 1m/s. Consider the density of water is 1000 kg/m^3.
Think about how the pressure is different at each height and how that contributes to the overall force.
Calculate the momentum flux for a flow with an average velocity of 20 m/s and a density of 800 kg/m^3 during laminar conditions.
Ensure you visualize how the area comes into play in this calculation.
