- At 32°C (90°F) and 15% relative humidity, air may be cooled to nearly 16°C (60°F).
- At 32°C (90°F) and 50% relative humidity, air may be cooled to about 24°C (75°F).
- At 40°C (105°F) and 15% relative humidity, air may be cooled to nearly 21°C (70°F).

How much humidity is too much for an evaporative cooler?
when the humidity reaches the dew point your cooler will not have any effect at all, lessening effect up to that point. However, you can still get relief from the fan running.
What is the relative humidity when the air is at its dew point?
100%
What is the relative humidity when the air temperature is at its dew point?
It is 100%.
What are the most common types of measurements performed by industrial humidity instruments?
Wet-bulb/dry-bulb humidity, relative humidity, vapor pressure, and dew point are the most common types of measurements performed by industrial humidity instruments.
What is the relative humidity when the air temperature is at dew point?
When the air temperature reaches the dew point, water droplets that are in the air become visible. This is how you would get fog. Relative Humidity goes soaring to near 100%.

What temperature is swamp cooler air?
It is a function of the "dew point" of the air at any given moment. If relative humidity is high, the dew point will also be high and the swamp cooler air will be relatively warm. If relative humidity is low, the dew point will also be low and the swamp cooler air will be relatively cold. A swamp cooler in Phx AZ will put out air about 30 degrees less than the outside air, and works more efficiently when the humidity outside is very low.
Does a swamp cooler work better in sun or shade?
The Unit being in Sun or Shade will have NO effect on how well a Swamp Cooler performs. Operation of Swamp / Evaporative Cooler effectiveness is determined by Ambient temperature / dew point and relative humidity. They are optimum in Dry / Hot / Low Humid climates such as found in the South West Desert areas of the U.S. The higher the Humidity / Dew Point, the LESS EFFECTIVE a Swamp / Evaporator Cooler will be. They cool by adding moisture to the Air. So the higher the Humidity is, the more the moisture content is in the air already, thus being less effective. Air can only support so much moisture before it starts to condensate. ( You will then start to feel Sticky and less comfortable ) Again, the Unit being in the Sun, verses being in the Shade, WILL NOT change the Coolers effectiveness in operation.
What is an Evaporative Cooler?
Update:Evaporative cooling is just that... using a liquid to cool a space by evaporating the liquid. You can effectively cool air down to the dew point temperature (100% saturated) for given initial conditions. These work best in dry climates. See a psychometric chart for more information. The liquid itself doesn't need to be at a lower temperature than the space you're cooling.Evaporative cooling is when the cooler liquid that isleft behind and cools the surface it rests upon.Evaporative Cooler is also known as a swamp cooler. It is a cooling machine which can be used in homes or offices for creating much more efficient surroundings.
What isThe opposite of evaporation?
Condensation is the opposite of evaporation this is known to happen at dew point when suspended water known as and measured as relative humidity drops out of suspension from the surrounding air and forms on cooler surfaces as water
What is the only way to change dew point?
to change dew point, humidity must be changed. an increase in humidity will result in a higher dew point and vice versa.
How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
How are temperature and humidity not related?
By marriage. Humidity and temperature are related. The maximum absolute humidity increases with temperature and pressure (up to the boiling point).
How can you read humidity on chart reading?
To read humidity on a chart, locate the humidity scale on the chart. Typically, humidity will be represented as a percentage. Identify where the data point falls on the scale to determine the humidity level at that particular time.
What is the relative humidity when the air is at its dew point?
100%
What is the affect of cooling on humidity ratio?
Cooler air cannot hold as much water vapor as the same volume of warmer air, so as the air temperature drops, the relative humidity increases, even when the amount of water vapor in a certain volume of air, or absolute humidity, remains unchanged. If the relative humidity reaches 100%, the air has all the water vapor that it is able to hold. If the temperature continues to drop beyond that point, the excess moisture in the air condenses as dew or frost.
Why does salt make ice cooler?
Salt does not make ice cooler; it lowers the freezing point.
