    viscosity calculation

    using ASTM D 341, If I had two values of viscosities at two different temperatures I could fit those values in the above equation and found the fuel constants A and B and then interpolate to find the value of viscosity at a different temperature. Presently, I know the viscosity of a Heavy Fuel...
