What is coefficient of viscosity?
  • 1 answers

Meghna Thapar 4 years, 2 months ago

The coefficient of viscosity is a measure of resistance to flow of the fluid. ... Dynamic viscosity μ is used in Darcy's law to calculate the rate of fluid flow in porous media. The relationship between viscosity and flow rate defines the rheology of the fluid. The SI unit of viscosity coefficient (η) is Nm-2s or Nsm-2.  It is the ratio of the actual velocity to the theoretical velocity of a fluid jet.
