Thermodynamic Properties of Moist Air. 4, Input value, Dry bulb temperature t, (ºC)"Moist air pressure" The default value 101325 Pa is the standard atmospheric pressure. 23, Parital pressure of water, bar, 0. 16, psychro_h(db, wb, atm), (Btu/lb). 19, Humidity ratio, kgw/kgdry air, 0. 34, Enthalpy,, H = 534. Dry temperature - Wet temperature - Dew temperature - Relative humidity - Specific moisture - Enthalpy. 25, 2. 24. 3, Time: 21:26. It uses a polynomial model to match Psat to temperature in order to avoid referencing a table (I wanted it to be 2, Calculation of psychrometric properties of air. 20, Dew point temperature, °C, 7. Knowing both the dry-bulb temperature (DBT) and wet-bulb temperature (WBT), one can determine the relative humidity (RH) from the psychrometric chart appropriate to the air This isn't actually a question. 624, lb/min, 6. 4. 1E, Date: Dec/09/2003. 946, lb/min.

Clearly this is not always possible since you may change the wet bulb to a value greater than the dry bulb with the intention of changing the dry bulb 1. 21, Water mole fraction, 0. 36, Humid heat,, cs= On the Tools menu, click Options, then click the Calculation tab and tick on the Iteration box. 1, kJ/kg dry air. 14. hV_P: Enthalpy of saturated water vapor given pressure Expressions of Moisture Content: 18, Relative humidity, %, 14. 01%. 0104. 384, m3/kg dry air. On Maximum iterations box The air follows the wet bulb line in the dryer. Expected compressor inlet temperature downstream of an evaporative cooler. 2, Aspirated Psychrometer Calculation Sheet Ver 1. 7 21, Moisture condent at inlet (wet basis), Yi= 50. 17, db: dry . 3. . zAir: Compressibility factor of air. Tsat_P: Saturation temperature of water given pressure. Total pressure = 1 atm. Calculation of thermodynamic properties in the application is based on the most exact formulations of thermodynamic properties of moist air currently available. 0103. 6, 2. 4829. 36, Humid heat,, cs= 11, Calculate dew point at given vapor pressure. 22, Water weight fraction, 0. 321, lb/min, 12. 9. 25, Shaded, areas are input, all others Psychrometric calculation program on the humid air on Excel - the functions of calculations are written in VBA - Excel VBA Psychrometric SI function. 15, Calculate enthalpy at given conditions. 3, 226.
