 From the value of formula_35 one can obtain the final Mach number (formula_37) and the other flow properties.As Mach number varies from 1 to formula_38, formula_39 takes values from 0 to formula_40, where

This places a limit on how much a supersonic flow can turn through, with the maximum turn angle given by,

One can also look at it as follows.A flow has to turn so that it can satisfy the boundary conditions.
