Yes, the runoff coefficient is typically dimensionless. It represents the ratio of rainfall runoff to total rainfall, and as a ratio, it does not have any physical units.
The coefficient of friction is not always constant as it can vary depending on factors like materials in contact, surface roughness, and presence of lubricants.
The coefficient of friction is determined by the nature of the materials in contact, surface roughness, pressure between the surfaces, and the presence of any lubricants or contaminants. It is a dimensionless quantity that represents the ratio of the force of friction between two surfaces to the normal force pressing the two surfaces together.
The coefficient of friction is a dimensionless number that quantifies the amount of resistance between two surfaces in contact with each other. It is determined experimentally and varies depending on the materials and surface conditions of the objects in contact. A higher coefficient of friction indicates greater resistance to sliding or movement.
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
In fluid dynamics, the drag coefficient and Reynolds number are related. The drag coefficient is a measure of how much resistance an object experiences when moving through a fluid, while the Reynolds number is a dimensionless quantity that describes the flow of the fluid around the object. Generally, as the Reynolds number increases, the drag coefficient decreases, indicating that the object experiences less resistance as the flow becomes more turbulent.
The coefficient of friction is dimensionless; it has no units.
It is a dimensionless parameter since its just a ratio between two quantities of same unit.
The coefficient of friction is dimensionless.
The coefficient of friction is not always constant as it can vary depending on factors like materials in contact, surface roughness, and presence of lubricants.
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.

The coefficient of friction is a unitless value because it represents a ratio of the force required to move an object over a surface to the weight of the object. Since it is a ratio of two forces, it does not have any units associated with it.
The stormwater runoff coefficient is determined by analyzing the land use, soil type, slope, and drainage characteristics of a specific area. It is calculated by dividing the amount of rainfall that runs off a surface by the total amount of rainfall that falls on that surface. This coefficient helps in estimating the amount of stormwater runoff that can be expected from a particular area during a storm event, which is crucial for designing effective stormwater management systems. Various methods and equations, such as the Rational Method or the SCS Curve Number method, can be used to determine the stormwater runoff coefficient based on these factors.
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.
the dimensionless numbers have the definition as that of dimensionless groups, and have all the properties which dimensionless groups have.
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.
Angles are not dimensionless.
