Re: Vapor Pressure
Vapor Pressure is a measure of the actual water content in the air. Water Grains are also a measure of the actual water content in the air. The SAE chose Vapor Pressure for their Dynamometer Correction Factor, and that's why I use it exclusively.
Relative Humidity is derived from both moisture content and temperature and is used to indicate how a human feels in certain atmospheric conditions. It is of no use for predicting the effect of atmospheric conditions on a race car.
Relative Humidity: Noun, the moisture on your ball sack when you are banging your sister in law.
See you at the races,
