The coefficient of friction is always?
A. dimensionless
Why is Rittinger constant dimensionless?
KR and KK are not dimensionless.
Does a dimensionless quantity have a unit?
"Dimensionless" means it doesn't have a unit.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
Is there any physical quantity having no dimension but unit only?
Yes. Look at the Wikipedia aritcle on "dimensionless quantity". Here are two examples: 1. Angles, when measured in radians, can be considered the ratio of the arc of a circle to the radius. The result is a dimensionless number. 2. The coefficient of friction, which is the ratio between two forces. Dimensionless quantities often appear as a result of taking the ratio of two measurements.
What are the units that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
What are the units of the coefficient of friction?
The coefficient of friction is a scalar quantity which has no direction which does not have an angle.
Coefficient of discharge is a dimensionless parameter?
It is a dimensionless parameter since its just a ratio between two quantities of same unit.
What unit of measure is used to measure friction?
The coefficient of friction is dimensionless.
The coefficient of friction is always?
A. dimensionless
How do you you determine storm water runoff coefficient?
A simple coefficient chart works best. However, in the event you do not have access to such a chart; here is the general coefficient information that can be used to calculate Storm water Runoff: 1) Smooth, Impervious Surfaces, i.e., Tile, Roofing materials, Concrete walkways has a runoff coefficient of approximately 90% 2) Gravel surfaces and paved asphalt surfaces have a runoff coefficient of about 80% 3) Mitigated, engineered and or loose soils have a coefficient rating of 60% 4) Natural soils like that found in an undisturbed forest has a general coefficient rating of approximately 30% 5) Built landscape areas like "Green Roofs" should hold to and strive to reach the target of a 30% runoff coefficient rating. Use this calculation to calculate runoff: (CA) X (R) X (E) X (0.6) = Area runoff in gallons. Understanding the equation: (CA) = Catchment area in Sq. Ft. i.e., 1 Acre = 43,560 Sq.Ft. (R) = Rainfall expressed in inches (E)= efficiency expressed in decimal (0.6) = Gallons per Square feet for every inch of rain
What is coefficient of static force?
i guess the question should be coefficient of static friction force.if it is so then it is just a dimensionless quantity signifying the degree to which the frictional force can oppose relative motion and prevent any relative motion.

What is the manning resistance coefficient for unfinished concrete in English units?
First, Manning's roughness coefficient is dimensionless. Second, usually unfinished concrete is assigned an n value of 0.014 whereas finished concrete is assigned an n value of 0.012.
What are dimensionless numbers?
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
What is the metric unit for friction?
A friction is a force, so it would be measured in newtons. The coefficient of friction, on the other hand, is a ratio between two forces, so it is dimensionless.
Why angle has a unit in spite it is dimensionless?
Angles are not dimensionless.
