5 cards from this section. Quick, good the night before a test.
What does the conservation of mass state?
Think about a system where mass stays the same.
Name one type of control volume.
Consider whether the volume stays still or changes shape.
What does the conservation of mass imply?
Think about a closed container.
The Reynolds transport theorem relates to which aspect of fluid mechanics?
Consider mass in a defined area.
A pipeline transports water at 5 m/s with a diameter of 0.1 m. Calculate the mass flow if the water density is 1000 kg/m³.
Use mass flow rate formula: ρAV.
If a tank has an inflow rate of 3 m³/s and an outflow rate of 2.5 m³/s, determine the change in water volume over 10 seconds.
Look at the difference between inflow and outflow rates.
