Question

Fluid Mechanics - True or False

1) Reynolds number represents the ratio of viscous force to the inertia force.
2) The entrance length (Le) for turbulent flow is greater than that for laminar flow for the same pipe diameter.
3) Increase the fluid viscosity leads to decrease the turbulence.
4) For laminar steady flow between parallel fixed plates, the pressure drop increase with increasing the thickness of the fluid layer between them.
5) For laminar steady flow for pipe, the pressure drop increase with increasing the pipe diameter.
6) For the same Reynolds number, friction factor for steady laminar flow between parallel plates is greater than that for pipe flow.
7) For turbulent flow, the thickness of viscous sublayer is greater than the thickness of inertial sublayer.
8) Darcy -Weisbach equation can be used for calculating the head of losses for both laminar and turbulent flow.
9) Minor losses important only for turbulent flow.
10) Minor losses for entrance flow conditions is less than that for exit flow conditions.

Only state if its False or True for each point.

Answer 1

Hello student as u mentioned to say only true or false but according to me explaination is required for your concept clearification so I had also explained reason behind it.

Please rate me thumbs up for the solution.
