• It is essential for analyzing fluid flow in systems.

• It is used for structural load calculations.

What does the continuity equation state about flow rates?

• Flow rate is equal to the sum of pressures.

• Flow rate is independent of area.

• Flow rate is equal to the product of area and velocity.

• Flow rate is inversely proportional to velocity.

How is the flow rate at point A related to points B and C?

• QA is independent of QB and QC.

• QA is equal to QB times QC.

• QA is equal to QB minus QC.

• QA is equal to QB plus QC.
