Ratio of static to the freestream pressure with freestream Mach number Calculator

The ratio of static pressure () to freestream pressure () with perturbations, often denoted as , is a dimensionless parameter used in fluid dynamics and aerodynamics to describe the pressure variation at a specific point in a fluid flow that includes perturbations or disturbances. 
  • Ratio of static to the freestream pressure (p/p∞)
  • Specific heat ratio (γ)
