Gas Dynamics
Flow relations, such as isentropic, normal shock, Rayleigh, Fanno, and
              Prandtl-Meyer
Calculate flow relations for Fanno lines, isentropic, normal shock, Prandtl-Meyer
              functions, and Rayleigh lines. When possible, these functions assume perfect gas
              environments. Each function has an mtype argument that lets you
              specify the inputs for the flow.
