Question

It's really a Geography lab course

The air inside a room is at temperature of 70 degrees Fahreinheit and has a mixing ratio of 7.6g/kg.

a) what is the relative humidity?

b) what is the dew point?

c) if the room temperature decreases by 10 degrees Fahrenheit per hour, how many hours will it take for the air to reach saturation?

d) after reaching saturation, if thr temperature of the room continues to decrease for one more hour, how many grams of water vapor (per kg pf air) will have had to condense out of the air to maintain a relative humidity of 100%?

Step 1

On calculating the relative humidity using the equation:

Step 2

Dew point can be calculated by using the equation:

Step 3

At the saturation point, the relative humidity of the system is 100%.

The initial temperature is 700F. For 100% relative humidity, the saturation mixing ratio is equal to actual mixing ratio...
