Question
Download Solution PDFCalculate the Reynolds number if the kinematic viscosity of water is 0.01 × 10-4 m2/s, which is flowing through a pipe of diameter 200 mm with the velocity of 5 m/s.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Reynolds number: The type of flow in which the fluid particles move along a well-defined streamline or paths, such that all the streamlines are straight and parallel to each other is known as laminar flow.
It is the ratio of Inertial force to the viscous force.
For pipe flow \(R_{e} = {\rho VD \over \mu}\) = \( {\rho VD \over \rho \nu} = {VD \over \nu} \)
Given
kinematic viscosity of water, \(\nu \) = 0.01 × 10-4 m2/s
pipe of diameter,D = 200 mm =0.2 m
velocity,V = 5 m/s
Calculation
Re = \({5\times0.2\over 0.01\times 10^{-4}}\) = 1000000 = 1 × 106
