The Universal Gas Constant (R_universal) is a fundamental constant in thermodynamics and is used to relate the properties of gases in various systems, including aircraft design and propulsion analysis. Its formula and SI unit are as follows:
This constant relates the physical properties of gases, such as pressure, volume, temperature, and the number of moles of gas, through the ideal gas law:
- P is the pressure of the gas in pascals (Pa).
- V is the volume of the gas in cubic meters (m³).
- n is the number of moles of the gas in moles (mol).
- T is the temperature of the gas in kelvin (K).
- R is the universal gas constant.
