When fluid is incomprehensible then A)velocity of the fluid is constant B)flow of fluid is along straight line C)density of fluid is constant D)volume of fluid is constant?

Question

Answer

Option d is correct ... I think.
because if the volume remain constant that means ...
fluid neither be expended nor be compressed .

Answer

Both C and D are correct. because incompressible fluid  is defined as whose density does not change on applying pressure

Answer

It's c and d because fluid is incomprehensible

Answer

Introduction:
When fluid is incomprehensible, it means that the fluid cannot be understood or described using a simple mathematical model. Incomprehensible fluid behavior is often encountered in complex flows where turbulence and interactions between different fluid regions occur. In such cases, certain properties of the fluid remain constant while others may vary.

Constant Velocity:
When fluid is incomprehensible, it does not necessarily mean that the velocity of the fluid is constant. In fact, the velocity of the fluid can vary throughout the flow field. Turbulent flows, for example, are characterized by high velocity fluctuations and irregular motion. Therefore, option A is incorrect.

Straight Line Flow:
Incomprehensible fluid behavior does not imply that the flow of the fluid is always along a straight line. Fluid flow can be highly complex and exhibit various patterns, such as vortices, eddies, and swirls. These flow patterns can occur in both steady and unsteady flows. Hence, option B is also incorrect.

Constant Density:
When fluid is incomprehensible, the density of the fluid can still remain constant. Incomprehensibility refers to the complexity of fluid behavior, not necessarily its density. Density is a fundamental property of the fluid and can be constant in both incomprehensible and comprehensible flows. Therefore, option C could be correct in certain cases, but it is not a definitive characteristic of incomprehensible fluid behavior.

Constant Volume:
When fluid is incomprehensible, the volume of the fluid is not necessarily constant. Incomprehensible flows can involve changes in volume due to compression or expansion. For example, in a turbulent flow through a constriction, the fluid may experience a decrease in volume as it passes through a narrower section. Therefore, option D is incorrect.

Conclusion:
In summary, when fluid is incomprehensible, it does not imply a constant velocity, flow along a straight line, constant density, or constant volume. Incomprehensible fluid behavior is characterized by complex flow patterns, turbulence, and variations in different fluid properties. It is important to consider the specific context and characteristics of the flow when determining the effects of incomprehensibility on different fluid properties.
