This friction is the effect of (linear) momentum exchange caused by molecules with sufficient energy to move (or "to jump") between these fluid sheets due to fluctuations in their motion. You can buy a convenient Sutherland formula viscosity calculator Excel spreadsheet for a very reasonable price. Concentrations can be calculated by molarity or percentage. 1.1 This practice covers the procedures for calculating the estimated kinematic viscosity of a blend of two or more petroleum products, such as lubricating oil base stocks, fuel components, residua with kerosine, crude oils, and related products, from their kinematic viscosities and blend fractions. This Excel spreadsheet is intended to calculate gas viscosity at a specified temperature using Sutherlandâs formula. See the blended calculated Kin.
