Isentropic Flow Calculator app for iPhone and iPad

Have you ever been in design review and wanted to make a quick compressible, isentropic flow calculation, but not had your gas tables handy?

This app uses the compressible, isentropic flow relationships, assuming ideal gas properties, to calculate the relationship between the following parameters.
• Mach number (Mn)
• Ratio of specific heats (gamma)
• Total pressure to static pressure ratio (P0/p) and its inverse (p/P0)
• Total temperature to static temperature ratio (T0/t) and its inverse (t/T0)
• Total temperature to static temperature ratio (T0/t) and its inverse (t/T0)
• Total density to static density ratio (Rho0/rho) and its inverse (rho/Rho0)
• Ratio of the 1D duct area to the 1D duct area at the sonic throat (A/A*) and its inverse (A*/A)

Unlike some other apps that only allow users to input Mach number and gamma to calculate the other parameters, this app allows you to input any of these parameters and calculates consistent values for all the other parameters.
