Viscosity Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Viscosity Number = (Flow Time of Polymer Solution/(Flow Time of Solvent-1))/Polymer Concentration
VN = (t/(t_o-1))/c
This formula uses 4 Variables

Variables Used

Viscosity Number - The Viscosity Number provides a measure of the molecular mass of a polymer.
Flow Time of Polymer Solution - (Measured in Second) - Flow Time of Polymer Solution is the total amount of time a polymer solution spends during the test.
Flow Time of Solvent - (Measured in Second) - Flow Time of Solvent is the total amount of time a solvent spends during the test.
Polymer Concentration - (Measured in Gram per Milliliter) - The Polymer Concentration is the total amount of concentration of a polymer in a solution.

STEP 1: Convert Input(s) to Base Unit

Flow Time of Polymer Solution: 2000 Second --> 2000 Second No Conversion Required
Flow Time of Solvent: 30 Second --> 30 Second No Conversion Required

What is Viscosity Method?

Viscometry or viscosity method was one of the first methods used for determining the MW of polymers. In this method, the viscosity of polymer solution is measured, and the simplest method used is capillary viscometry by using the Ubbelohde U-tube viscometer. In this method, both the flow time of the polymer solution (t) and the flow time of the pure solvent (t0) are recorded.

How to Calculate Viscosity Number?

Viscosity Number calculator uses Viscosity Number = (Flow Time of Polymer Solution/(Flow Time of Solvent-1))/Polymer Concentration to calculate 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 calculate Viscosity Number using this online calculator? To use this online calculator for Viscosity Number, enter Flow Time of Polymer Solution (t), Flow Time of Solvent (t_o) & Polymer Concentration (c) and hit the calculate button. Here is how the Viscosity Number calculation can be explained with given input values -> 60.49607 = (2000/(30-1))/1140.
