Huggins Equation

• is specific viscosity.
  
  
• c is concentration (I need to look up typical units; for now, just make sure everything cancels out.)
  
  
• is intrinsic viscosity.
  
  
• k' is a constant; perhaps you could call it the Huggins constant, but I haven't seen a textbook author do that.
  
  
• The Huggins Equation is concerned with intrinsic viscosity experiments.
  
  • see viscosity.
    
    

If you plot (specific viscosity divided by concentration) as a function of c, concentration, then at zero concentration, specific viscosity divided by concentration is intrinsic viscosity. This is shown on the graph below as a yellow function. A similar calculation may be performed with relative viscosity using the Kraemer Equation.
