The Reynolds number is a dimensionless number used to categorize the fluids systems in which the effect of viscosity is important in controlling the velocities or the flow pattern of a fluid. It is a function of fluid density, velocity, diameter and inversely proportional to viscosity. A liquid flows in a circular tube at temperature with a Reynolds Number of 1000.

The Reynolds number is a dimensionless number used to categorize
the fluids systems in which the effect of viscosity is important in
controlling the velocities or the flow pattern of a fluid. It is a function
of fluid density, velocity, diameter and inversely proportional to
viscosity.
A liquid flows in a circular tube at temperature with a Reynolds
Number of 1000. In a dynamically similar situation, the same liquid
flows through a tube whose radius is twice as long as the radius of the
fırst tube. If u is the kinematic viscosity of the fluid at that particular
temperature, then the product of velocity of fluid and the tube radius
in the second tube is
