Fluid kinematics: name the type of flow with no change of volume or density During the motion, the fluid's volume and density remain constant everywhere. Choose the correct term for this flow.

Q: Fluid kinematics: name the type of flow with no change of volume or density During the motion, the fluid's volume and density remain constant everywhere. Choose the correct term for this flow.

Concept/Approach If density does not change during motion, the flow is called incompressible. Uniform and steady describe spatial and temporal constancy of velocity, not density. Final Answer Incompressible flow
