Velocity is not typically associated with a compression tester in the context of aircraft design. Compression testers are tools used to measure engine cylinder compression in piston engines. The primary measurement is the pressure, not velocity.
The velocity of a fluid in an aircraft engine component (such as a nozzle or compressor) can be calculated using the formula:
- V = Velocity (in meters per second, m/s)
- ṁ = Mass flow rate of the fluid (in kilograms per second, kg/s)
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- A = Cross-sectional area through which the fluid is flowing (in square meters, m²)
