Calculation of contact angle?
Angle of contact is the angle between a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute . For convex surface , it is obtuse.
How do you measure the contact angle?
There are many ways to measure a contact angle, but the simplest way is to use a goniometer. The image of the droplet is taken with a high resolution camera; the angle can then be measured using a protractor.
The angle between a tangent and the radius of a circle att the point of contact is?
It is a right angle
Definition of lift angle?
The angle of rotation of the balance in which the roller pin is in contact with the pallet forks.
What describes the angle between water level and the incline of a water ski ramp?
An acute angle
What is contact angle in penetrant test?
The contact angle is the angle in which the liquid interface meets the solid surface. The contact angle should be as small as possible to have an effective penetrant material.
Why does water have a meniscus if you put it inside a graduated cylinder?
It is a problem of surface tension of water and contact angle between water and glass (or a plastic).
Is alumina hydrophobic or hydrophilic?
More towards hydrophilic. It forms a contact angle of 10 degrees when in contact with water. Means it "attracts" water molecules to itself, more than, say, Zirconia (another form of similar oxide, called Zirconia Dioxide), which forms a contact angle of 50 degrees with water to material. (water droplet appears more round, so this means it doesn't attracts water as strong as alumina).
What is the unit of angle of contact?
Contact angle is the angle that a drop of liquid makes as it meets the surface or interface of another phase, usually a solid
Is aluminum oxide hydrophilic or hydrophobic with water?

What has the author Chien-kuo Yang written?
Chien-kuo Yang has written: 'Use of the equilibrium contact angle as an index of contact surface cleanliness' -- subject(s): Contact angle, Surfaces (Technology), Analysis
The bond angle in a water molecule is?
The water molecule's bond angle is about 104.45 degrees.
What is the adjacent side of a right triangle?
A right angled triangle has three sides. The naming of these sides is dependant on which angle you are observing. The first side is named the opposite and is the side which is not in contact with the angle that is being observed (each angle is in contact with ONLY two sides) The second side is the hypotenuse which is the side opposite to the right angle. Also termed the diagonal, the hypotenuse is the longest side of the triangle. The third side, the one you are interested in, is the adjacent side which is the angle which is in contact with the angle being observed which ISN'T the hypotenuse or the opposite. It can be determined by a process of elimination in that there are two sides in contact with the observed angle.
