WebThe dew-point temperature is the temperature below which water condenses out of air. You can also read the dew-point temperature directly from a Psychrometric chart. … WebFor any type of psychrometric process the rate of energy transfer to or from the air may be simply determined from the chart using the relationship Power (kW) = mass flow rate (kg/s) × enthalpy change (kJ/kg) = ṁΔh. So P = 0.75 × (66.0 – 40.5) = 19.1kW. This may be split into the power used to provide the sensible and latent cooling and ...
WebUS Weather Bureau Psychrometric Tables (WB-235) $ 6.50. The US Weather Bureau Psychrometric Tables are used for determining the relative humidity and dew point temperature from the dry and wet bulb temperature readings on sling or battery-powered psychrometers. The tables cover the range of 23.0 to 30.0 inches barometric pressure.
