How is Reynolds number dependent on the viscosity of fluid?
Directly proportional
Inversely proportional
Not effected by viscosity of fluid
None
How can we calculate the value of Reynolds number.
Viscous force / Initial force
Initial force × viscous force
Initial force / viscous force
None
If the value of the Reynolds number is <1000, then the nature of flow of fluid is
Slow
Turbulent
Laminar
Viscous
Which of the following statement is true for the Reynolds experiment?
If dye filament forms straight line, then it is called as laminar flow.
If dye filament flows in a slightly wavy manner, then it said to be transition flow.
If dye filament diffuses over the entire cross section of the tube while passing, then it is called as turbulent flow.

Which dye is basically used in the Reynolds experiment?
Potassium permanganate solution
Anthraquinone dye
Aniline dye
None
Reynolds number is which type of quantity
Scalar
Vector
Dimension less
none
If we increase the diameter of pipe through which the fluid is flowing, what effect will be there on the value of Reynolds number
Increases
Decreases
first decreases and then increases
first increases then decreases
what is the applications of Reynolds number
Predict the direction of fluid flow
Study the rate of sedimentation
calculate the total mechanical energy

If the floe of fluid is turbulent then the value of Reynolds number must be
> 2000
between 2000 and 4000
< 2000
> 4000
