What is difference between velocity and density?
Seismic velocity is defined as the speed with which a seismic wave travels through a medium and is measured in km/s. The density is the mass per unit volume and is expressed in g/cc.
What is the relation between viscosity and velocity?
A simple formula representing this relationship is: (1-1) where v equals velocity, η equals viscosity, and r is the hydrodynamic radius of the molecule. Thus, the force sensed by a molecule increases as the velocity, viscosity, or size of the molecule increases.
What is the difference between the density and viscosity?
In fluid dynamics, viscosity is the parameter to measure the thickness or thinness of any given fluid. Density is the measure of spaces between two particles in a given fluid.
What are the two types of viscosity and what is mathematical relation between them?
There are two kinds of viscosity commonly reported, kinematic and dynamic. Dynamic viscosity is the relationship between the shear stress and the shear rate in a fluid. The Kinematic viscosity is the relationship between viscous and inertial forces in a fluid.
What is the relationship between velocity and density?
Therefore, the equation indicates that the velocity is inversely proportional to density.
From this formula, it is obvious that velocity is inversely proportional to the square root of the density of the medium. It means that if the density increases, the velocity decreases.
How do you find the density of viscosity?
Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid. Plug your measurements into the equation to calculate the viscosity of the liquid.
What is the relationship between viscosity and fluidity?
viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow.
Does velocity increase with density?
When a body moves through a medium, the medium may exert a frictional force and the force would be greater if the surface of contact is greater. So a body having the same density but different volume would be affected. So, velocity will be less when the volume is greater.
What is the difference between density and viscosity?
Answer: We define density as the measurement of the molecular weight of the molecules of gas/liquid/fluid. Density equals the number of molecules x molecular weight per volume occupied, while viscosity is a measurement of the intermolecular forces between the molecules in a gas/liquid/fluid.

What is the difference between velocity and density?
Velocity is a measurement of speed in a particular direction. V = displacement/ time Velocity is a rate because it involves time. Density is the measurement of mass per unit volume. D = m/v That is it!
What is the effect of temperature on viscosity?
In general, for any fluids, when the temperature is increased, its density decreases, thus the fluid becomes less viscous. In fluids, Kinematic viscosity is the ratio of dynamic viscosity to density.
What is the unit of absolute viscosity?
Absolute viscosity is a parameter for measuring the internal resistance in the fluid. =Density of the liquid or fluid or air. In MKS (Meter-kilogram-second), the unit of the density is kgm⁻³. In CGS or Centi-gram-second, the unit of the density is gcm⁻³.
