Relative humidity and static discharge

WebMoisture makes the air more conductive, so it can absorb and more evenly distribute excess charges. On humid (wet) days, objects don’t hold static charges quite as well. Also, … WebAn increase in relative humidity (RH) reduces flow and power, and a decrease in RH will increase flow and power. The addition of water vapor to the air makes air humid and reduces the density of the air. This is due to the molar mass of water being less than that of air (See Figure 4). Higher relative humidity: Decreases the discharge pressure ...
