Viscosity Number Solution

Follow our step by step solution on how to calculate Viscosity Number?

FIRST Step Consider the formula

VN = \frac{\frac{t}{t o - 1}}{c}

Next Step Substitute values of Variables

∴

VN = \frac{\frac{2000s}{30s - 1}}{1.14g/mL}

Next Step Prepare to Evaluate

∴

VN = \frac{\frac{2000}{30 - 1}}{1.14}

Next Step Evaluate

∴

VN = 60.4960677555959

LAST Step Rounding Answer

∴

VN = 60.4961

How to Evaluate Viscosity Number?

Viscosity Number evaluator uses Viscosity Number = (Flow Time of Polymer Solution/(Flow Time of Solvent-1))/Polymer Concentration to evaluate the Viscosity Number, The Viscosity Number formula provides a measure of the molecular mass of a polymer. It is the limiting value of the specific viscosity/concentration ratio at zero concentration. Viscosity Number is denoted by VN symbol.

How to evaluate Viscosity Number using this online evaluator? To use this online evaluator for Viscosity Number, enter Flow Time of Polymer Solution (t), Flow Time of Solvent (t_o) & Polymer Concentration (c) and hit the calculate button.

FAQs on Viscosity Number

What is the formula to find Viscosity Number?

The formula of Viscosity Number is expressed as Viscosity Number = (Flow Time of Polymer Solution/(Flow Time of Solvent-1))/Polymer Concentration. Here is an example- 60.49607 = (2000/(30-1))/1140.

How to calculate Viscosity Number?

With Flow Time of Polymer Solution (t), Flow Time of Solvent (t_o) & Polymer Concentration (c) we can find Viscosity Number using the formula - Viscosity Number = (Flow Time of Polymer Solution/(Flow Time of Solvent-1))/Polymer Concentration.
