On Psychrometric Chart Relative Humidity Lines Are?

The relative humidity lines in the psychrometric chart are curved lines that move upwards to the right. The line representing saturated air where the relative humidity - RH is 100% - is the uppermost curved line in the chart.

What is relative humidity in psychrometric chart?

According to the psychrometric chart, if the relative humidity of the outside air is 80% and the outside air temperature is 85°F, when the air is cooled to 55°F, vapor will condense out of the air, and the relative humidity will be 100%.

How do you find relative humidity in a psychrometric chart?

Take a ruler and draw a vertical line at the dry bulb temperature of 70 and draw a horizontal line where the dew point is 50. The point where these two lines intersect is known as a 'state point'. Plot the state point and you can also read the rel- ative humidity, wet bulb, enthalpy, vapor pressure and humidity ratio.
