## 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/(to-1))/c
This formula uses 3 Variables
Variables Used
Flow Time of Polymer Solution - Flow Time of Polymer Solution is the total amount of time a polymer solution spends during the test. (Measured in Second)
Flow Time of Solvent - Flow Time of Solvent is the total amount of time a solvent spends during the test. (Measured in Second)
Polymer Concentration - The Polymer Concentration is the total amount of concentration of a polymer in a solution. (Measured in Gram per Milliliter)
STEP 1: Convert Input(s) to Base Unit
Flow Time of Polymer Solution: 2 Second --> 2 Second No Conversion Required
Flow Time of Solvent: 3 Second --> 3 Second No Conversion Required
Polymer Concentration: 1 Gram per Milliliter --> 1000 Kilogram per Meter³ (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
VN = (t/(to-1))/c --> (2/(3-1))/1000
Evaluating ... ...
VN = 0.001
STEP 3: Convert Result to Output's Unit
0.001 --> No Conversion Required
0.001 <-- Viscosity Number

## 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.
