What is critical flow in fluids?
Critical flow exists when at a fixed upstream pressure the flow cannot be further increased by lowering the downstream pressure. Flow is proportional to the square root of the pressure drop.
What is the relation between viscosity and flow-ability of a material?
The higher the viscosity, the lower the flow-ability of a material.(Viscosity=internal resistance to flow)
Electrons do not readily flow through what material?
The material that electrons do not readily flow through in the electrical trade is classed an an insulator.
What material permits electron to flow?
Conductors.
What is a material through which electricity does on flow?
water
What is flow stress?
flow stress is yield stress of material during plastic deformation
Do solids like ice flow?
Any material can flow under stress.
What is critical pressure in nozzle?
Critical pressure in a nozzle is the pressure at which the flow of material through the nozzle reaches its maximum. Beyond which any increase in pressure will not result in an increase in flow. The point at which the velocity of a fluid in the throat of the nozzle reaches the local speed of sound, creating a sonic wave, or a sonic choke.

What is a material that can flow easily called?
A material that can easily flow is called a fluid.
What flows indefinitely in a superconductor?
A current of electricity can flow at the same strength for an indefinitely long time in a superconductor but only for as long as the superconductor is held below its critical temperature. If its temperature were allowed to rise to its critical temperature - or higher - the material would no longer behave as a superconductor: it would acquire resistivity which would restrict the flow of current.

The higher the viscosity, the lower the flow-ability of a material.(Viscosity=internal resistance to flow)

What is critical velocity in fluid flow?
The flow of a liquid remains steady or orderly only so long as its velocity does not exceed a certain limiting value for it, called critical velocity.
Electrons do not readily flow through what material?
The material that electrons do not readily flow through in the electrical trade is classed an an insulator.
What is critical flow and sub critical flow of fluids?
Critical flow is the special case where the froude number (dimensionless) is equal to 1. i.e. The velocity divided by the square root of (gravitational constant multiplied by the depth) =1. Sub critical flow i has a froude number less than 1, and is therefore characterised by slow moving deep water. Supercritical flow is defined as having a froude number greater than 1 and is therefore characterised by shallow fast moving flows.
Critical flow factor?
there is no such things like that in the whole world
