ESDU 80015 gives dynamic viscosity data at saturation pressure for 55 alkenes, straight chain up to C20 and branched chain up to C10. The data were critically evaluated and fitted by a single equation for which the coefficients for each compound are provided. The values are tabulated at intervals of 10 K from the melting point to 0.9 of the critical temperature. Data for some compounds have been estimated and this is clearly indicated. Guidance on the effect of pressure is also given.
