The Law of the Ellipse, or Stodola's cone law,[1][2] attributed to Aurel Stodola, provides a method for calculating the highly nonlinear dependence of extraction pressures with a flow for multistage turbine with high backpressure, when the turbine nozzles are not choked.[3] It is important in turbine off-design calculations.
