- research of mixture "air and water vapor" features
- both mass transfer and heat transfer
- enthalpy potential
Psychrometric chart
- operating pressure eg.1atm (7 properties)
- enthalpy
- sat temp
- dry ball temp
- wet ball temp
- RH (relative humidity)
- specific volume
- absolute humidity
- Saturated line
- left : saturated ; right : superheated (oure water)
- dew-pt temp
- RH (phi)
- def : wet air (water vapor mole ratio) / same P T sat air (water vapor mole ratio)
- by ideal gas eq : water vapor pressure / same P T pure water sat pressure
- Absolute humidity ratio (W)
- def : water vapor(kg) / dry air (kg)
- for specific atmpsphric pressure for one chart
- Enthalpy
- dry air (h)_ 0 oC air + water vapor (h)_0oC sat water
- Specific Volume
- Wet ball temp
- Straight-line law
Ideal gas assumptions
- low pressure (<< sat pressure) , high temperature (>> sat temperature )
- const specific heat
- for general water vapor and air
