Solution:
Reynolds number (Re) is defined as the ratio of inertial forces to viscous forces and it is a dimensionless quantity used in fluid mechanics to predict flow patterns in different fluid flow situations.
Reynolds number formula:
Re = (ρVD)/μ
Where,
ρ = density of fluid
V = velocity of fluid
D = diameter of the pipe
μ = dynamic viscosity of fluid
Given data,
Length of pipe (L) = 5.0 m
Diameter of pipe (D) = 0.20 m
Reynolds number at inlet (ReD) = 500
Velocity profile:
Uniform at inlet and parabolic at exit.
Reynolds number at the exit of pipe:
Since the diameter of the pipe (D) remains constant, the Reynolds number is directly proportional to the velocity (V) of the fluid.
As the velocity profile at inlet is uniform, the velocity of fluid remains constant throughout the length of the pipe.
Therefore, the Reynolds number remains constant throughout the pipe.
Thus, the Reynolds number at the exit of the pipe is also 500, same as that of inlet.
Hence, the correct answer is '500'.
