Weblower limit is -2500 J/kg, then the humidity is h r = exp (7.3 × 10⁻⁶ × - 2500) = 0.98 so the relative humidity in the soil is around 98%. Sag ebrush can go lower than -2500 J/kg. Researchers have measured -7000 J/kg under it at the end of the growing season, but even that is around 95% humidity. The conclusion is that the humidity Web4 dec. 2024 · Enter the air temperature (C) and wet bulb or dew point temperature or RH. All other values, except wet bulb, will be recalculated when you click or tab away from the entry box. Click on the " Lock DP " box to enter a new temperature at the same dew point. This allows calculation of the RH that the air will acquire at a different temperature.
Web8 nov. 2024 · Relative humidity (RH), which is expressed as a percentage, measures the amount of moisture currently in the air relative to the total amount of moisture that the … WebThe equation for relative humidity, RH = condensation rate evaporation rate × 100% , shows that its essentially a comparison between the condensation rate and the evaporation rate. Since relative humidity depends on both the condensation rate and the evaporation rate, it depends on both dew point and temperature.
