On a winter day when the air temperature is 0 °C, the relative humidity is 50% . Outside air comes inside and is heated to a room temperature of 20 °C . What is the relative humidity of the air inside the room. (Does this problem show why inside air is so dry in winter?)
If the room temperature is 23℃ and the relative humidity (RH) is 50%, what is the dew point??
A sling psychrometer can measure humidity because
Answer,
the dry bulb will measure the same temperature no matter how much water is in the air.
Answer,
the cooling of the wet bulb is independent of the amount of water in the air.
Answer,
the heating of the dry bulb is proportional to the amount of water in the air.
Selected Answer,
the cooling of the wet bulb is proportional to the amount of water in the air.
Answer,
the heating of the wet bulb is proortional to the amount of water in the air.
Answer,
the cooling of the dry bulb is proportional to the amount of water in the air.
