andrewsforest.oregonstate.eduea is the actual vapor pressure or vapor pressure at dewpoint temperature es is the saturation vapor pressure or vapor pressure at air temperature it can be shown that: Dew point temperature = Tdew = (237.3*X) / (17.269‐X)
How to Estimate Reid Vapor Pressure (RVP) of Blends
www.bre.comNew restrictions on vaporization loss of petroleum products give added emphasis to the measurement of vapor pressure for petroleum fractions and their blends. The common method for measuring vapor pressure is the Reid vapor pressure (RVP) test. Now an algorithm is available to calculate RVP without performing the actual test.
