Question

compare and contrast the molecular and convective mechanism for momentum transport​

Answer 1

Answer:

The simple shear flow between parallel plates and how momentum is transferred through the fluid by viscous action. This is an elementary example of molecular momentum transport. that momentum can also be transferred by the bulk fluid motion and that such convective momentum transport is proportional to the fluid density.

Answer 2

Compare and contrast the molecular and convective mechanism for momentum transport​

• Typically, a vertical flux of the momentum of horizontal winds or currents is referred to as convective momentum transport. As a non-conserved flow tracer, that momentum is transferred by vertical air motions during convection.
• The phenomenon known as "molecular momentum transfer" occurs when particles in a liquid that are subject to a force push nearby particles to move in the same direction.
• Random fluid molecule motions between various layers are what cause the transfer of molecular momentum. As a result of this transfer's propensity to equalize the velocities of adjacent layers, it opposes the relative motion of those layers. Compared to gases, liquids' molecules are significantly more densely spaced.
• Regardless of any interactions between the system's components, the total linear momentum of a system of particles that is not subject to external forces is constant in magnitude and direction.
