## What is the dimension formula of viscous force?

According to Newton, the viscous force acting between liquid layers of area A and velocity gradient ΔvΔz is given by F=−ηAdvdz, then the dimensions of η are. [ML−2T−2]

## What is the dimensional formula of wavelength?

Therefore, the wavelength is dimensionally represented as [M0 L1 T0].

What is ETA formula?

ETA is purely a statistical term and based on simple formula i.e. Time (ETA) is equal to distance divided by speed of travel, transportation. This small concept is very useful in business planning and management.

What is the unit and dimension of viscosity?

dimensions. In viscosity. The dimensions of dynamic viscosity are force × time ÷ area. The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units.

### What is the unit of viscous force?

The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.

### What is viscosity coefficient and write the unit dimension of viscosity?

Coefficient of viscosity is defined as tangential force required to maintain a unit velocity gradient between two parallel layers of liquid of unit area. Mathematically, Coefficient of viscosity (η)= Fr/Av where F = tangential force, r = distance between the layers , v = velocity. Dimensional Formula of Force = M1L1T-2.

What is the dimension of wavelength and frequency?

[M0L−1T0]

What is the dimensional formula of wavelength and frequency of a wave?

Let M-mass, L-length, T-time. (These are the physical quantities in which dimensions are expressed.) Dimensional formula: M0 L0 T-1 (here 0 and -1 are the exponents).

## What is the value of ETA in physics?

1.000
Electronics, η stands for the ideality factor of a bipolar transistor, and has a value close to 1.000.

## What is the formula of coefficient of velocity?

The velocity coefficient can be calculated as the square root of slope divided by roughness.

What is viscosity give its dimension?

Viscosity: The property of a fluid which opposes the relative motion between the layers is called viscosity. Units of C.G.S: Coefficient of viscosity = poise. The dimensional formula = ML-1T-1.

What is the dimension of force?

Or, F = [M] × [L1 T-2] = M1 L1 T-2. Therefore, Force is dimensionally represented as M1 L1 T-2.

### What is the formula for coefficient of viscosity?

Coefficient of viscosity (η)= Fr/Av where F = tangential force, r = distance between the layers , v = velocity. Was this answer helpful?

What is the dimension of viscosity?

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 ]. Therefore, viscosity is dimensionally represented as [M1 L-1 T-1]. ⇒ Check Other Dimensional Formulas:

What does the viscous force depend on?

Stoke found that the viscous force F depends upon (i) coefficient of viscosity, η of the medium, (ii) terminal velocity, v of the body and (iii) radius, r of the spherical body. This can be written as.
