4 cards from this section. Quick, good the night before a test.
Define the continuity equation in terms of fluid flow.
Think about mass conservation.
What is incompressible flow?
Consider fluids like water.
What does the continuity equation represent?
Remember the principle of mass in closed systems.
True or False: Incompressible flow means the density changes with the flow.
Think about common fluids like water.
A tank has a rectangular base with dimensions 4 m x 3 m and a height of 5 m. Water flows through a pipe from this tank at a rate of 0.5 m³/s. If the pipe diameter changes from 10 cm to 5 cm, calculate the velocity at both sections and discuss how the continuity equation is used.
Use A = πr² for cross-sectional area calculations.
Design a scenario involving a pipe network used in a municipal water system where the continuity equation needs to be applied to determine pressures and flow rates. Explain your design.
Focus on where water enters and exits different pipe sizes.
