23 Apr 2018 A psychrometric chart can be used in two different ways. The first is done by plotting multiple data points, that represent the air conditions at a 22 Jul 2014 where P is the standard atmospheric pressure 101.325 [kPa]. The saturation curve (100% relative humidity) also known as the dew point curve is 10 May 2019 A climate's dry bulb temperature increases as its dew point (DP) and wet bulb ( WB) temperatures decrease. Psychrometric charts show this by better understanding of air properties and the psychrometric chart to the wet bulb and the dew point temperature scale line. Index: General Agriculture.

The psychrometric chart represents the state of a given atmosphere by a point which gives the dry-bulb, wet-bulb, relative humidity, specific volume and

1) On the psychrometric chart locate value 78 o F on the DB temperature scale located at the bottom of the chart. 2) Locate WB temperature of 65 o F on the saturation curve scale. 3) Extend the vertical line (constant DB temperature line) from 78 o and the diagonal line (constant WB temperature line) from 65 o F and get the point of intersection of the two lines, which indicates the condition of the given air.
This only affects the psychrometric chart, the relative humidity chart scale is always 0 to 100%.

A psychrometric chart is a graph of the physical properties of moist air at a temperature, the dew point temperature, the relative humidity, the humidity ratio, index 1 denotes the first sample properties and index 2 denotes the second. Standard psychrometric charts are bounded by the dry-bulb temperature line When constant specific humidity lines meet RH = 100 % are called Dew Point
