Hs = (0.6207)*(PH2O/(1-PH2O))
This formula uses 2 Variables
Variables Used
Saturation Humidity - Saturation Humidity is defined as the absolute humidity of vapour-gas mixture at 100% saturation.
Vapour Pressure of Water at DBT - (Measured in Pascal) - Vapour Pressure of Water at DBT is the pressure exerted by water vapor which are in thermodynamic equilibrium with its condensed phases (solid or liquid) in a closed system at a given temperature.
STEP 1: Convert Input(s) to Base Unit
Vapour Pressure of Water at DBT: 0.892 Pascal --> 0.892 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Hs = (0.6207)*(PH2O/(1-PH2O)) --> (0.6207)*(0.892/(1-0.892))
Evaluating ... ...

What is Saturation Humidity?

Saturation humidity is the maximum amount of water vapor air can hold at a given temperature and pressure. From a chemical engineering standpoint, this concept is vital in various industrial processes. Maintaining precise humidity levels is critical in chemical reactions and manufacturing to ensure product quality, control, and integrity. Deviations from saturation conditions can lead to undesired reactions, product quality issues, and equipment corrosion. Thus, understanding and managing saturation humidity is essential for optimizing industrial operations and ensuring consistent results.

What is Humidification Process?

The humidification process involves adding moisture to indoor air to increase its relative humidity. It begins by measuring the current humidity level using a hygrometer. A desired humidity level is set, typically between 30% and 60%. Different humidification methods like evaporative, steam, or ultrasonic are chosen based on space requirements. The humidifier, often equipped with a humidistat, is then operated to release moisture. As the humidifier maintains the setpoint, it continuously monitors and controls humidity levels. Regular maintenance is essential to prevent issues and ensure safe and effective operation, especially in dry environments or during winter when indoor heating can dry out the air.
