Hello students, mainly the two aspects of fluid flow in pipes are laminar flow and turbulent flow.
00:08
So we have two types of flow laminar and turbulent.
00:13
So we are comparing these two based on reynolds number.
00:18
So we have the equation for reynolds number re is equal to rho into u velocity into diameter divided by viscosity.
00:31
So we can define the terms that is rho is density, u that is the velocity flow, b is the diameter and mu is viscosity of the specific viscosity.
00:50
So in the case of laminar flow we have the value of reynolds number should be typically greater than 2, 0, 0, 0.
01:09
So laminar means it is smooth, steady and streamlined path, the property of laminar and we have the velocity is parabolic.
01:32
Advantage of laminar flow is it have lower loss of energy as due to less frictional forces and it cause less damage to pipes.
01:59
And the disadvantages of the laminar flow it is not effective in heat transfer process...
