Is relative dielectric constant dimensionless?
Correct: it is a dimensionless number.
How do you prove dimensionless groups?
A dimensionless number has no units. The units of all variables that compose the dimensionless number (product or ratio) must cancel each other.
Can a quantity have constant value and be dimensionless?
Yes. Conversion factors will generally be dimensionless constants.
What is the rule of dimensionless quantity?
infinity
Is angle is dimesionless?
No, but an angle is dimensionless.
What are dimensionless numbers?
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
Why angle has a unit in spite it is dimensionless?
Angles are not dimensionless.
Is relative dielectric constant dimensionless?
Correct: it is a dimensionless number.
Does a dimensionless quantity have a unit?
No, a dimensionless quantity does not have a unit because it represents a pure number without any physical dimension. Examples of dimensionless quantities include ratios, proportions, and mathematical constants.
How do you prove dimensionless groups?
A dimensionless number has no units. The units of all variables that compose the dimensionless number (product or ratio) must cancel each other.
Which dimensionless quantity has unit?
If a quantity is "dimensionless", that means it has no units, and it's just a number.
Can a quantity have constant value and be dimensionless?
Yes. Conversion factors will generally be dimensionless constants.
Is specific weight is a dimensionless quantity?
energy/mass example: calories/gram
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
Are points dimensionless?
Yes.
Coefficient of discharge is a dimensionless parameter?
It is a dimensionless parameter since its just a ratio between two quantities of same unit.
What is a dimension of a point?
Points are dimensionless.
