Performs oil blending calculations using the W. The version 2 release of VISDISK has added a graphing capability and an NBS “best-fit” computation that analyzes multiple kinematic viscosity data points and selects the optimum viscosity curve for the sample data provided. Test data can also be used to generate a complete interpolation report at temperature increments specified by the user. An interpolation component calculates viscosity at any specified temperature or temperature at a desired viscosity. VISDISK facilitates calculation/verification of kinematic viscosity by providing a data table for input, and then performing complex viscosity and density calculations. VISDISK also provides supporting data analysis capability for several equipment items manufactured by CANNON, including the PolyVISC, Cold-Cranking Simulator (CCS), Bending-Beam Rheometer, and the CANNON Mini-Rotary Viscometer (CMRV). The VISDISK program brings computerized solutions to many difficult computational problems associated with kinematic viscosity determination.
