5) In a steamy sauna, the wall is colder than the rest of the sauna. The sauna starts off at a relative humidity of 0.60 and steam is continously added to the sauna. If the wall stays at a constant temperature of 15 celcius, what is the water vapor partial pressure (kPa) next to the wall when condensation forms? 6) For atmospheric air at dry bulb temperature of 30 celcius and wet bulb temperature of 25 celcius, what is the...

We are learning about relative humidity. 1st part- what is the water vapor content at 25 degree C air if its relative humidity is 50%? 50=10/20 x 100% gives me the water vapor content of 10g/kg. 2nd p...
We are learning about relative humidity. 1st part- what is the water vapor content at 25 degree C air if its relative humidity is 50%? 50=10/20 x 100% gives me the water vapor content of 10g/kg. 2nd part- If the air was at 25 degree C at sea level, and rises to 1,000 meters, then what will its temperature be? It will drop by 10 degree C, so the temperature will be 15 degrees C. At 15 degree's C the...
