Do you remember how this thing works.

Moisture in the atmosphere: How does it get there?

How does moisture enter the atmosphere?

Evaporation

Define Evaporation

what speeds it up? Wind, heat, surface area

The glasses below are half-filled with water (50% full). Which glass contains more water?

•If air at 10°C can hold 10 gallons of water, and 5gallons are present, what % of the air is full of water? _______

•If the air can hold 10 gallons, and 10 gallons are present, what % of the air is full of water? ____________

The amount of moisture in the air is referred to as?

When the air is completely full of water it is considered?

How is it measured ?

Air temp = 84 Dew Point temp = 61High or Low pressure? Will a wet towel dry

quickly or slowly today?

Air temp 64 Dew Point temp 64Pressure system? Towel dry fast or slow

Ever notice how you feel cold when you get out of the shower or pool?

That’s because evaporation is a heating process.

Water needs heat in order to evaporate and therefore it gets the

heat from your Body.

The same thing happens when you use a sling psychrometer.

Because evaporation is pulling the heat out of the thermometer, the wet bulb is always colder than the

dry bulb (or the same temp)

Think about this. If it is raining out, will there be a lot of evaporation taking place

So what will happen to the wet bulb temperature?

Find the Dew Point for the following.

Dry bulb temp =-8 Wet Bulb = -9

Dry Bulb = 20 Wet Bulb = 16

Dry bulb = 2 R.H = 67. What is the Wet bulb Temp?

Dry Bulb = 16, Dew Point = 11, what is the Relative Humidity?
