Eswb=saturation vapor pressure at the wet bulb temperature(mb) P=atmospheric pressure at surface~1013 mb at sea-level. But before the vapor pressures can be computed, the air temperature and/or dewpoint temperature must be converted to degrees Celsius (°C). To check you have the right ratio for the engine you're using, check in the operating manual. Step 1. This is defined as the ratio of actual humidity ratio to the humidity ratio of a saturated mixture at the same temperature and pressure. If partly saturated air is cooled without changing its pressure or amount of water vapor, a point is reached when it becomes saturated. Mol. If you put gasoline in a two-stroke engine without oil in the engine will fail. In order to calculate the mixing ratio, a saturated vapor pressure (es) must be computed for values of air temperature, and an actual vapor pressure (e) must be computed for values of dewpoint temperature.
