Conductivity of Ethanol 85
Ethanol 85 or E85 is probably the most widely used of the ethanol-gasoline blends at the present time.We know a value of 25 pS-1 would…

Reid Vapor Pressure of Gasoline
Clearly with blends low in ethanol such as E5 and EIO the chief determinant in the vapour pressure will be the reid vapor pressure of the…
