In aircraft design, the density (ρ) of the fluid or air flowing through a convergence duct is a fundamental parameter. The formula for density in a convergence duct can be defined as:
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- P = Pressure of the fluid (in pascals, Pa)
- R = Specific gas constant for the fluid (in J/(kg·K))
- T = Temperature of the fluid (in kelvin, K)
