In aircraft design, a compression tester is not typically associated with a density formula. Compression testers are tools used to measure engine cylinder compression in piston engines. They do not have a direct relationship with density in the same way that, for example, air or fuel components in the engine might.
Density is typically calculated using the ideal gas law for gases like air:
– Density (ρ) is measured in kilograms per cubic meter (kg/m³).
– Pressure (P) is measured in pascals (Pa).
– The Gas Constant (R) for dry air is approximately 287.05 J/(kg·K).
– Temperature (T) is measured in kelvin (K).
