The Kinematic viscosity is not a dimensionless parameter m2/sec.
So, the correct opinion is D
So, the correct opinion is D

Since all are dimensionless except kinematic viscosity and are also applicable to flowing liquids but kinematic viscosity is not applicable although it has dimension. So the correct answer is "d".

The dimensionless parameter that is not applicable to flowing liquids is the Pressure coefficient (Option 3).
The pressure coefficient is commonly used in aerodynamics and fluid dynamics to analyze pressure distribution around objects in fluid flow, such as airfoils. It is not a parameter specifically associated with flowing liquids but rather used for analyzing fluid behaviour around solid objects in motion.

Only the kinematic viscosity is dimensional parameter which cannot be applied to any dimensionless parameters of flowing fluid.

Option D.
Kinematics viscosity = dynamic viscosity/density.
Other options have not any unit.
It means that other dimensionless parameters.
Kinematics viscosity = dynamic viscosity/density.
Other options have not any unit.
It means that other dimensionless parameters.

Question clearly stated that 'DIMENSION LESS parameter NOT APPLICABLE'.
So the only option having dimension is kinematic viscosity, So, the answer is 'D'.
So the only option having dimension is kinematic viscosity, So, the answer is 'D'.

The answer given is right because here asked about dimensionless not applicable to, so the only option is kinematic viscosity which has unit m2/sec, all another are dimensionless.

The answer will be B.
As all other parameters, we use in fluid flowing.
Reynolds num, pressure coefficient in flow chart, friction factor in headless, kinematic viscosity ney and also all parameters other than kinematic viscosity(m^2/sec) are dimensionless.
