Question
Write the application of viscosity?

Answer

Following application of viscosity are as follow :
(1) It is necessary to provide lubricant oil in machines. While choosing any lubricant oil, its coefficient of viscosity has to be kept in mind as well as it has to be seen that there is minimum change in it due to increase in temperature. In different machine, different lubricant have to be supplied according to the season. The lubricant oils provided in bicycles and motors are different.
(2) The coefficient of viscosity is used to equalize the velocity of a moving object in order to slow it down.
(3) Molecular weight is also determined from the value of coefficient of viscosity and it is also used in determining the complex compound structure.
