What is the SI unit of kinematic viscosity and dynamic viscosity?
The SI unit for kinematic viscosity is square meters per second (m2/s). However, due to the viscosity values of most common fluids, square centimeters per second (cm2/s) is used more often.
What is the difference between viscosity and kinematic viscosity?
Dynamic viscosity is measure of fluid’s resistance to shear flow when some external force is applied. Kinematic viscosity is ratio of dynamic viscosity to density of that fluid. It is measure of fluid’s resistance to shear flow under the weight of gravity.
What is the difference between kinematic viscosity and dynamic viscosity?
Kinematic viscosity incorporates fluid density as part of its measurement. Thus, dynamic viscosity is a measure of force, while kinematic viscosity is a measure of velocity. That’s the difference. If you divide kinematic viscosity by the fluid density, you get absolute viscosity.
What is the kinematic viscosity of oil?
While the descriptions may seem similar, there are important distinctions between the two. An oil’s kinematic viscosity is defined as its resistance to flow and shear due to gravity. Imagine filling a beaker with turbine oil and another with a thick gear oil.
What is the kinematic viscosity of air?
The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 × 10– 5 kg/(m·s) , 18.1 μPa·s or 1.81 × 10– 5 Pa·s . The kinematic viscosity of air at 15 °C is 1.48 × 10– 5 m2 /s or 14.8 cSt.
Is kinematic viscosity constant?
The time is converted directly to kinematic viscosity using a calibration constant provided for the specific tube. The unit of measure of kinematic viscosity is Centistokes (cSt). A basic difference between the dynamic and kinematic viscosity measurements is density.
What is molecular viscosity?
At a molecular level, viscosity is a result the interaction between the different molecules in a fluid. This can be also understood as friction between the molecules in the fluid. Just like in the case of friction between moving solids, viscosity will determine the energy required to make a fluid flow.
What are the dimension of viscosity?
Or, η = [M1 L1 T– 2] × [M0 L2 T0]– 1 × [M0 L1 T– 1]– 1 × [M0 L1 T0] = [M1 L– 1 T– 1]. Therefore, viscosity is dimensionally represented as [M1 L– 1 T– 1].

Which of the following represent Kinematic viscosity?
Notes: Kinematic viscosity is defined mathematically as the ratio of the viscosity of a fluid to its density. It is the measure of the resistive flow of a fluid under the influence of gravity.
What is the SI unit of viscosity Mcq?
The SI unit of viscosity is poiseiulle (Pl). Its other units are Nsm-2 or Pa s.

What is the dimensional formula of ML 1t 2?
ML– 1T– 2 is the dimension of any quantity that is force per unit area such as Pressure or Stress, Young’s Modulus, Bulk Modulus, Modulus of Rigidity, Energy Density. The Modulus of Elasticity is the ratio of the stress applied to a body or substance to the resulting strain within the elastic limit.
What is the dimensional formula of kinetic energy?
Therefore, Kinetic Energy is dimensionally represented as [M1 L2 T– 2].
What is the dimension of discharge?
Discharge = V x D x W If length is measured in feet and time in seconds, Discharge has units of feet3/sec or cubic feet per second (cfs). Depth times Width gives the cross-sectional area. The shape of the channel is important because of the reduction in velocity due to friction along the channel margins.
Which of the following represent correct dimension of the coefficient of viscosity?
ML−2T−2.
What is the dimension formula?
Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. … These will specify the nature of the unit and not its magnitude.
How do you calculate the coefficient of viscosity?
Dynamic viscosity is related to kinematic viscosity by the equation μ = ρν where ρ is the density of the fluid. The unit of dynamic viscosity μ is centipoise. If fluid density ρ has the unit of g/cc, then kinematic viscosity ν has the unit of centistoke. Thus, 1 centistoke equals 1 centipoise divided by 1 g/cc.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
