viscosity of hyper-saline solutions
 

viscosity of hyper-saline solutions.

I am trying to find a simple calculation that will enable me to approximate the viscosity of a hyper-saline solution at various temperatures.

I have an equation for viscosity of water at various temperatures, derived from a data table, and another equation for viscosity of a water/salt solution at various concentrations from 0 to 20% at 20 degrees C.

Can the viscosities from each be multiplied with each other so I can approximate viscosities for various solutions at various temperatures?
