How is relative humidity calculated
WebWelcome to the Dew Point Calculator Use the sliders to explore combinations of temperature (T), relative humidity (RH), and dew point (DP) to compare the preservation quality of your environment. Knowing the dew point can help achieve long-term preservation of collection materials for libraries, museums, and archives. Webwhere T is the ambient temperature in °Celsius, RH is relative humidity (%), A 1 = 17.625, B 1 = 243.04°C. [2 p.226] Enthalpy (h) h, kJ/kg = T × (1.01 + 0.00189 × W) + 2.5 × W …

This Hyperphysics article contains some empiric formulas and graphs that will help you determine the density of the saturated vapor as …
WebRelative humidity can be described as e/es which is the ratio between the vapor pressure and saturation vapor pressure, or w/ws which is the ratio of water vapor's mass mixing ratios at their actual and saturation levels. Specific humidity is defined as the mass mixing ratio water vapor in air at actual and saturation values. WebRelative Humidity is measured using a device called a sling psychrometer.This consists of 2 side by side conventional thermometers, one of which (the wet bulb thermometer) has a wetted wick placed at the …
