The relation between viscosity and density can be explained by the kinematic viscosity equation.
. Up to 10 cash back Explanation. We are given the mass of the baseball outside of the water. G is a constant which is 98 ms2.
V frac mu rho frac 067 N s per square m 10 kg per cubic m 0067 m2 s -1 Therefore the kinetic viscosity is 0067. It also focuses on mathematical equations so lets discuss the density viscosity equation. The formula for Dynamic Viscosity.
Torque required to turn the probe. Where v is the kinematic viscosity μ is the absolute viscosity ρ is. Therefore the density of a fluid is 30612 kgm3.
The kinematic viscosity in formula is. The SI unit for viscosity is newton-second per square meter Nsm2. Density is normally expressed as kg per cubic meter.
Viscosity 2 x ball density liquid density x g x a2 9 x v where g acceleration due to gravity 98 ms2 a. Since dynamic viscosity is the tangential force required to move one. The Mass Density when Viscosity is Known.
Kinematic viscosity is defined by the ratio of dynamic viscosity and fluid density. The formula for the conversion from kinematic to dynamic and from dynamic to kinematic is. The unit of dynamic viscosity μ is centipoise.
The general viscosity formula dictates that viscosity shear stressshear rate velocity gradient The coefficient of viscosity can be derived as the following. The final equation youll need to calculate the liquids viscosity is this. If fluid density ρ has the unit of gcc.
ρ 3 098 ρ 30612 kgm 3. In fluid dynamics it is sometimes more appropriate to work in terms of kinematic viscosity sometimes also called the momentum diffusivity defined as the ratio of the dynamic. A subject like Physics does not rely on theoretical knowledge only.
It is directly proportional to the absolute viscosity but inversely proportional to the density of the fluid. Viscosity is determined by measuring the force ie. However youll often see viscosity expressed in terms of pascal-second Pas kilogram per meter per second.
The mass of a material substance per unit volume is called Density. Viscosity and Density Equation. The term viscosity refers to the resistance to flow.
Dynamic viscosity is related to kinematic viscosity by the equation μ ρν where ρ is the density of the fluid. The density is given by ρ νμ. Calculate viscosity of liquid from the data you have collected.
Absolute viscosity μ 098 Nsm 2. Density is calculated using the formula dMV where d represent. Kinematic Viscosity Dynamic Viscosity Density v ì p Centistokes Centipoise Density To understand the metric units involved in this relationship it will be necessary to use an example.
Viscosity Force Area Velocity-1 Distance between layers Or η M 1 L 1 T -2 M 0 L 2 T 0 -1 M 0 L 1 T -1 -1 M 0 L 1 T 0 M 1 L -1 T -1. Kinematic viscosity ν 3 m 2 s. Using the weight equation with the gravitational constant being and the mass being the.
