How do you read a relative humidity chart?



How do you read a relative humidity chart?

Temperature vs. Humidity How to read the chart: find the temperature on the left hand side, then move to the right until you find the column for the approximate relative humidity. That number will be the temperature that it will "feel" like. Example: A temperature of 95 and relative humidity of 50% will "feel" like 107 degrees.

What is the relative humidity when the temperature is 73°F?

When the outdoor air is heated up to 73°F indoors, the absolute amount of water in the air is still the same. But since warmer air can hold more water, the relative humidity goes down to 33%.

What is humidity?

WHAT IS. HUMIDITY? Humidity is a measure of the amount of water vapor in the air. Relative humidity measures the amount of water in the air in relation to the maximum amount of water vapor (moisture). The higher the temperature, the more water vapor the air can hold. Relative humidity is what your morning weather reporter would refer to.

What does a 100% relative humidity level mean?

A 100% relative humidity level would mean that the air is completely saturated with water vapor. Unable to hold any more, it would rain. Colder climates often have lower humidity levels than warmer climates as colder air holds less moisture than warm air.

What is the relative humidity of the air?

The relative humidity is a measure of how moist the air is. We can define relative humidity as the actual amount of water vapor (moisture) present in the air compared to the total amount of water vapor that the air can hold at a given temperature. Note that we always express relative humidity as a percentage.

What is considered high humidity?

What Is Considered High Humidity? Humidity is the amount of water vapor present in the air "expressed as a percentage of the amount needed for saturation at the same temperature." The ability of the air to hold water changes as the temperature goes up or down.

What is a normal humidity level for an indoor house?

When the outdoor temperature is: Over 50˚F, indoor humidity levels should be less than 50% Over 20˚F, indoor humidity levels should be less than 40% Between 10˚F and 20˚F, indoor humidity levels should be less than 35%
