Nozzle Area Ratio Calculator

Calculate nozzle area ratio (A/A*) with varying Mach number and plot on a graph using simple rocket nozzle calculator online.

Nozzle Area Ratio Calculation

Formula:

[A / A×] = [1/m × (1+((k-1)/2)m)/(1+((k-1)/2))][k+2/(2(k-1))]

where,
A - cross-sectional area of nozzle passage at a given downstream location in nozzle
A* - cross-sectional area of nozzle throat
M - Mach number of flow at a given downstream location in nozzle
A/A* - nozzle area ratio

Note: both Mach number and area ratio are dimensionless.
