Webb1 Answer. A Psychrometric chart graphically represents the thermodynamic properties of moist air. Standard psychrometric charts are bounded by the dry-bulb temperature line (abscissa) and the vapour pressure or humidity ratio (ordinate). The Left Hand Side of the psychrometric chart is bounded by the saturation line. WebbBy using this formula and the psychrometric chart we know it will take 44094 Watts to cool 1000 l/s from 35°C dry bulb / 24°C wet bulb down to 12°C dry bulb / 12°C wet bulb. Along this journey we cooled air below its dew point and this caused the moisture to …

WebbPsychrometric processes include physical and thermodynamic properties such as dry bulb temperature, wet bulb temperature, humidity, enthalpy, and air density.
