"The friction factor is sometimes expressed in terms of the Fanning friction factor, which is one-fourth of the Moody friction factor. In some references the Moody friction factor is used, in others, the Fanning friction factor is used. Care must be exercised to avoid inadvertent use of the wrong friction factor." [1]

The Antoine equation for vapor pressure as a function of temperature is:
log10 P = A – B/(T + C) (1)
where P = vapor pressure, mm Hg
A, B, and C = Antoine coefficients
T = temperature, C
