It is possible to develop a relationship between λ and (the integral scale). We also know that

We have already seen that in a steady, homogeneous shear flow situation, one can write
|
|
or |
|
|
|
The ratio of is then given by

A in the above equation is an undetermined constant taken to be of order of unity. In all turbulent flows . Hence the Taylor microscale is quite small . This shows that dissipation of energy is due to small eddies of turbulence.
