Humidity
Absolute Humidity (as g/m3)
| D = | 804 1 + 0.00633t | x | e Po |
| = | H 100 | x | 804 1 + 0.00633t | x | e Po |
Dew Point Temperature (as °C)
| T = | 237.3/7.5 log e - 0.786 | - 1 |
| es = 6.1078 x 107.5t(237.3 + 1) |
Relative Humidity (as % RH)
| RH = | e es | x 100 = | D Ds | x 100 |
H = relative humidity (% RH)
Po = standard air pressure (mm Hg)
D = absolute humidity (g/m3)
e = water steam pressure (mm Hg)
Ds = absolute humidity in saturation (g/m3)
es = saturated water steam pressure (mm Hg)
t = temperature (°C)
T = dew point temperature
