WebFeb 2, 2024 · It is the mass of water vapor present in a unit volume of air. We can write the formula for absolute humidity as: H = \frac {m} {V} H = V m where: H H – Absolute humidity usually expressed in g/m 3; m m – Mass of water vapor; and V V – Volume of air and water vapor mixture. How to calculate relative humidity WebAt 15 degress the vapor pressure of water is 12.8 mm Hg. So that does agree with your intuition. At 15 degrees, the vapor only creates a pressure of 12.8 mmg Hg while at 25 degrees, the vapor creates a pressure of 23.8 mm Hg. Meaning, at 25 degrees, more water vaporizes to create a greater pressure. Comment.
