Question

is velocity of molecules same in all the layers in laminar flow?? explain your answer

Answer 1

Hello mate

No the velocity of molecules is not same in each layer of laminar flow.

This is so because of viscosity in fluids. This is the friction between the layers of fluid . Now as friction role is to oppose a motion , the top most layer has highest velocity and as we go down friction increases due to more normal force and hence the last layer ha the least velocity.

Answer 2

✌️The velocity of the upper layers increases as the distance of layers from the fixed layer increases.

..❤️. In laminar flow, the velocity of molecules Gradation of velocity in the laminar flow is not same in all the layers because every layer offers some resistance or friction to the layer immediately below it.
