**Introduction**

A Psychrometric Wheel Calculator is an innovative tool, a byproduct of advanced digital technology integrated with the fundamentals of psychrometry. This calculator simplifies complex calculations involving various atmospheric properties, enabling professionals and enthusiasts alike to understand and interpret diverse environmental conditions effortlessly.

**Definition**

The Psychrometric Wheel Calculator is a digital solution that mimics the functionalities of a psychrometric chart. In psychrometry, this chart is used to measure interrelated properties of air, including temperature, humidity, enthalpy, and others. The calculator brings this paper-based resource into the digital age, increasing accuracy and convenience in data interpretation.

**Detailed Explanations of the Calculator's Working**

At the core of the Psychrometric Wheel Calculator's working mechanism lies the psychrometric chart. This chart represents a plethora of complex calculations, providing vital data on air conditions. The calculator digitizes these calculations, requiring users to input specific values like dry-bulb temperature or dew point temperature. It then generates results, providing data like relative humidity.

**Properly Formatted Formula with Variables Description**

The Psychrometric Wheel Calculator uses intricate formulas. For instance, to calculate relative humidity, it uses: RH = 100*(EXP((17.625*DP)/(243.04+DP))/EXP((17.625*DBT)/(243.04+DBT))), where RH stands for relative humidity, DP for dew point temperature, and DBT for dry bulb temperature.

**Example**

Consider a scenario where you have a dry-bulb temperature of 25°C and a dew point temperature of 20°C. Inputting these values into the Psychrometric Wheel Calculator will return the relative humidity, which is approximately 69.34%.
