Pumpability is an important factor with all heat transfer fluids. This is dependent on fluid viscosity (as a function of temperature). While most thermal fluid manufacturers provide standard temperature-viscosity tables, you may find that there is no viscosity data reported for the temperature points that you are interested in. This Viscosity Calculator helps you to calculate viscosities across a range of operating temperatures. Our calculator is easy to use. All you need to generate viscosities at different temperature points is the viscosity-temperature data of the heat transfer fluid in question. Plug in viscosity data at two temperature points and include your desired operational temperature to calculate the corresponding viscosity.
