Estimate the amount of steam required (lb/h in 100 cfm) in humid air. Using steam to humidify air. Relative humidity in moist air can estimated by measuring the dry and wet bulb temperature. Maximum water content in humid air vs. temperature. The moisture holding capacity of air increases with temperature.

Psychrometric chart to analyze air properties, including temperature, humidity, enthalpy, and dew point at barometric pressure 29.921 inches of Mercury and temperature ranging 20 o F to 120 o F. The psychrometric chart below is made for standard atmospheric conditions.

Jul 12, 2023 · The humidity ratio, as seen on the vertical, y-axis scale, is a reliable indicator of air moisture level since it reflects the pounds of moisture contained in a pound of dry air and does not fluctuate with dry-bulb temperature readings as does relative humidity.

Jul 27, 2023 · Enter either the mass of the dry and wet air or the partial pressures of the dry and wet air into the calculator to determine the humidity ratio.

A convenient, precise and customizable psychrometric chart & calculator tool for HVAC engineers. Support IP and SI units.

In the chart settings (icon under the chart), you can adjust the Temperature Axis and Humidity Ratio Axis, enable and set your Comfort Area and define the Air Density. Axes : By adjusting the ranges, you can focus on just a part of the diagram.
