Simply spin the wheels to enter temperature and relative humidity. The app will output the corresponding dew point or grains per pound, giving….Psychrometric calculation by mixture of air with constant specific moisture. Weather data for thermal calculations. In program PYSCHROSI is integrated a library of the weather data defining the climatic parameters adopted in general for the dimensioning of the installations of air-conditioning. General definitions. In air-conditioning, it is of ...The Direct Evaporative Cooling Process in a Psychrometric Chart. Air at with dry bulb temperature 70 o F and relative moisture 60% (state A) is cooled down (state B) by evaporating water. The process is indicated in the psychrometric chart below. With 100% humidification of the air - the dry bulb temperature will approach 61 o F.This psychrometric calculator provides web bulb temperature and other psychrometric calculation in addition to a psychrometric chart. Either wet bulb temperature or relative humidity can be selected as input. You can enter also altitude, that is necessary to make corrections for the atmospheric pressure. A pressure of 1013.25 hPa is considered ...150 CFM + 1550 CMF + 300 CFM. Calculate the Wet Bulb Mixed Air Temperature: TMA,WB = 77oF x 150 CFM + 62.3oF x 1550 CMF + 54.5oF x 300 CFM = 62.23oF Wet Bulb. 150 CFM + 1550 CMF + 300 CFM. Our Online, Easy-to-User Calculator Allows Users to Calculate the Mixed Air Temperature of 2 or 3 Airstreams. Use in English or Metric Units.Calculate wind chill based on a Wind Speed of Mph.

Psychrometric chart for air at barometric pressure 29.921 inches of Mercury and temperature ranging 20 o F to 120 o F. UTM to Latitude and Longitude ConverterAbsolute humidity (AH) : AH, kg/m³ = P w ⁄ (R w × T) where P w is the water vapor pressure, T is ambient temperature in Kelvin, R w is specific gas constant for water vapor and it is equal to 461.5. This formula is derived from Ideal gas law, and adapted for water vapor. Dewpoint or dew point temperature (Td)This calculator estimates the temperature to which air must be cooled to become saturated with water vapor and form dew. Please provide any two of the three variables below to calculate the third. Air Temperature. Fahrenheit °F Celsius °C Kelvin. Relative Humidity. Dew Point Temperature. Fahrenheit °F Celsius °C Kelvin.The psychrometric chart is made with the PsycPro software available from www.linric.com. Transform between the Mollier diagram and the psychrometric chart; Standard Atmospheric Pressure = 1 atm = 101.325 kN/m 2 = 101.325 kPa = 14.7 psia = 0 psig = 29.92 in Hg = 760 torr = 33.95 Ft.H 2 O = 407.2 In.W.G .... ,
