PSYCROMETRIKsugiyantoGrafik psychrometrik berisikan lima property fisikuntuk mendeskripsikan udara, yaitu :Dry-bulb temperature ( temperatur bola kering)Wet-bulb temperature ( temperature bola basah)Dew-point temperature ( temperature pengembunan)Relative humidity ( kelembaban relatif)Humidity ratio ( rasio kelembaban )

Definisi Psycrometric

Diagram Psycrometrik

Kurva jenuh (saturation curve) yang merupakan 100 % RHGaris skala temperatur bola kering ( 0 % RH)Kondungan uap air atau skala ratio kelembaban (RH)

Letak garis dan skala pada grafik

1. saturation temperature2. dewpoint temperature3. enthalpy4. relative humidity5. humidity ratio (moisture content)6. wet bulb temperature7. volume of mixture8. dry bulb temperature.

Letak garis dan skala pada grafikPada musim panas diketahui dry bulb temperature 95 oF dan wet bulb temperature 78 oF, berapakah RH, humidity ratio dan dew point ?
