Area ratio calculator

The area ratio equation for nozzles is a fundamental formula used in fluid dynamics, particularly in the context of compressible flow through nozzles. It relates the cross-sectional area of the nozzle at the throat to the cross-sectional area at the inlet (or exit) of the nozzle. This ratio is crucial in determining the flow properties, such as velocity and pressure, through the nozzle.

The area ratio can be expressed mathematically as:

Where:

  • is the area ratio.
  • is the cross-sectional area of the throat (minimum area).
  • is the cross-sectional area at the exit (or inlet) of the nozzle.
