What is the laminar flow between two parallel plates?

For flow between parallel plates, the flow is laminar when Re < 1,400; whereas for pipe flow, the flow is laminar when Re < 2,100.

What is the significance of viscous flow through parallel plates?

. (See Figure 10.1.) Figure 10.1: Viscous flow between parallel plates. Note that this flux is directly proportional to the effective pressure gradient, inversely proportional to the fluid viscosity, and increases as the cube of the distance between the plates.

When considering a flow in between two parallel plates the ratio of maximum velocity to average velocity is?

The Questions and Answers of The ratio of maximum velocity to average velocity for steady flow between fixed parallel plates is:a)2/3b)4/3c)3/2d)2Correct answer is option ‘C’.

What is the shear stress between two parallel fixed plates?

The shear stress between two fixed parallel plates with a laminar flow between them. varies directly as distance from the mid-plane. varies inversely as distance from the midplane. varies parabolically across the gap.

How do we determine the total discharge through parallel pipes?

Explanation: Total discharge in parallel pipes are determined by adding the discharges so developed in individual pipes. If Q1 is the discharge through pipe 1 and Q2 is the discharge through pipe 2. Then the total discharge through parallel pipes is equal to Q1+Q2.

What do you mean by viscous flow?

noun. flow of a fluid in which its velocity at any point is constant or varies in a regular manner. It can be represented by streamlines. Also called: viscous flow.

What is the ratio of maximum velocity to average?

2
Ratio of maximum velocity to average velocity is 2.

What is the maximum velocity for laminar flow?

Detailed Solution. Explanation: For a fully developed laminar viscous flow through a circular pipe, the maximum velocity is equal to twice the average velocity. For the fully developed laminar flow through the parallel plates, the maximum velocity is equal to the (3/2) times of the average velocity.

What do you mean by Prandtl mixing length theory?

Prandtl’s mixing length theory is a 2-Dimensional model attempting to describe the momentum transfer within a turbulent fluid flow. OR simply It can be defined as the average distance that a small mass of fluid will travel before it exchanges its momentum with another mass of fluid.

What is plane Poiseuille flow?

Plane Poiseuille flow is flow created between two infinitely long parallel plates, separated by a distance with a constant pressure gradient is applied in the direction of flow.
