In an incompressible flow of fluid, the fluid ________________?
Correct answer: C. Density does not change with pressure & temperature
- A. Temperature remains constant
- B. Compressibility is greater than zero
- C. Density does not change with pressure & temperature
- D. Is frictionless
Explanation
Incompressible flow assumes that fluid density remains essentially constant despite changes in pressure and temperature. Constant temperature or frictionless motion is not implied by incompressibility.
