4 cards from this section. Quick, good the night before a test.
Define the continuity equation in fluid mechanics.
Think about the balance of mass entering and leaving a control volume.
What does the Reynolds transport theorem relate?
Consider how we analyze fluid flow in different perspectives.
What is the continuity equation?
Remember the balance of mass flow in and out of a control volume.
True or False: The Reynolds transport theorem is used exclusively for mass conservation.
Consider its broader applications in fluid mechanics.
A 10cm diameter pipe gradually narrows to 5cm. If water flows at 2m/s in the wider section, calculate the speed in the narrower section.
Remember to find both areas before calculating.
In a tank, water flows out at a rate of 3L/s. If the tank has a square base with a side of 1m, calculate how fast the water surface level drops.
Convert units and maintain consistency in measurements.
