# Suspension Fluid Calculators

The calculators below provide the basics for calculating the viscosity of a blended fluid.

## Specific Gravity Calculator

The SG is often not provided for fluids but can be calculated from the weight and volume of a fluid.

The SG for suspension fluids is normally between 0.8 and 0.9.

## Viscosity Calculator

This calculator provides the viscosity of a blended fluid based on the percentages of the source fluids.

Enter the viscosity and specific gravity your fluids plus the % for the first fluid then press calculate.

These calculations use the
Refutas Equation
