Any small instability in shape causes changes in the flow of fluid, which alters the shape further.
He found that Katerina had abnormal tonsils that were impeding the flow of fluid between the brain and the spinal cord, much the way a classic Chiari malformation would.
As a result of inflammation, the iris sticks to the lens or the cornea, blocking the normal flow of fluid in the eye.
At lesser throttle positions, the flow of fluid to the hydraulic chamber is reduced, and the valve opens only part way.
If the formation is quite productive, these perforations (usually about 30 cm, or 12 inches, apart) will be sufficient to create a flow of fluid into the well.
Like plaque in arteries, this accumulation restricts the flow of fluid and sometimes blocks things up completely.One way to keep the oil flowing is to heat the pipe.
This is entirely due to lateral flow of fluid mass and heat in the Y-direction.
Using Darcy's law, the flow of fluid depends on permeability, viscosity, and the pressure gradient.
In general, viscosity can be defined as the internal resistance to the flow of fluid.
Pressurising the propellant ensures there is a steady, even flow of fluid into the combustion chambers of the thrusters.
Permeability is a key parameter that governs the flow of fluid through a fractured rock mass.
