critical angle n. 1.The smallest angle of incidence at which a light ray passing from one medium to another less refractive medium can be totally reflected from the boundary between the two. 2.The angle of attack of an airfoil at which airflow abruptly changes, causing changes in the lift...
Also called angle of stall,. Aeronautics. the angle of attack, greater than or equal to the angle of attack for maximum lift, at which there is a sudden change in the airflow around an airfoil with a subsequent decrease in lift and increase in drag.Discover...

The critical angle of bubble formation (maximum angle of air entrainment measured from the horizontal) was measured for plunging liquid jets. Measurements were made on liquids with varying density, viscosity and surface tension, and also with jets of varying diameter, flow velocity and height. An ...
Each voxel is assigned a value on a scale in which air has a value of −1000; water, 0; and compact bone, +1000. intensive care unit see intensive care unit. International unit (IU) 1. a unit of enzyme activity equal to the amount of enzyme that catalyzes the conversion of one ...
There, air molecules are sparse and electrons have plenty of runway, so they can attain breakdown speed before they slam into a molecule. The Importance of Being Electric Depending on the system, the engine either can develop sea level manifold pressure up to a defined altitude--a turbo...
What is critical angle in refraction?Refraction:When light strikes an object it can bounce off of it, pass through it, or be absorbed by it. When light bounces off of an object it is either reflected or scattered, and when light passes through it is either transmitted or refracted. During...

I love my 823 and it's medium nib was a dream straight off - also I have no problems filling at an angle, which makes me wonder if you're just unlucky. However you're not alone - track down the YouTube video of Stephen Bre Brown on his - he also had nib problems, but he g...
