If the different layers of a fluid offer no resistance over each other, then the fluid will be a/ an
Correct answer: A. Ideal fluid
- A. Ideal fluid
- B. Viscous fluid
- C. Newtonian fluid
- D. Non-viscous fluid
Explanation
The correct answer is ideal fluid. An ideal fluid is a theoretical fluid that is incompressible and non-viscous, meaning it has no internal friction or resistance between its layers. This is why the layers of such a fluid can move over each other without any resistance. A viscous fluid contradicts this by having internal friction. A Newtonian fluid has a constant viscosity, meaning it still possesses some level of resistance, unlike an ideal fluid. Although a non-viscous fluid suggests no viscosity, the term 'ideal fluid' is more accurate in encapsulating the properties described in the question.

About Fluid Flow
Fluid flow covers pressure, density, viscosity and the motion of liquids and gases through pipes or open channels. It includes the continuity equation, Bernoulli equation, streamline and turbulent flow, and the effects of changing area, height and speed. Viscosity and ideal fluid assumptions must not be confused with pressure effects.
