What is coefficient of viscosity? |
| Answer» The\xa0coefficient of viscosity\xa0is a measure of resistance to flow of the fluid. ... Dynamic\xa0viscosity\xa0μ is used in Darcy\'s law to calculate the rate of fluid flow in porous media. The relationship between\xa0viscosity\xa0and flow rate defines the rheology of the fluid.\xa0The SI unit of viscosity coefficient (η) is Nm-2s or Nsm-2. It is the ratio of the actual\xa0velocity\xa0to the theoretical\xa0velocity\xa0of a fluid jet. | |
