Drying & Psychrometric Calc

Restoration and HVAC contractor's psychrometric calculator — grains per pound, dew point, relative humidity and drying performance, offline. PSYCHROMETRIC CALCULATIONS • Dry bulb, wet bulb and dew point relationships • Relative humidity from dry and wet bulb • Grains per pound (GPP) and g/kg • Enthalpy of moist air STRUCTURAL DRYING • Water vapour pressure differential • Dehumidifier pint-per-day sizing from GPP differential • Air mover CFM for drying chamber • Class 1/2/3/4 drying targets HVAC PSYCHROMETRICS • Sensible and latent heat ratio • Supply air temperature and humidity • Cooling coil performance estimation UNIT SUPPORT • °F/°C, GPP/g·kg⁻¹, BTU/lb / kJ/kg Offline — works without network.
