(double altitude, double pStag=101325., double TStag=288.15, double g=9.80665, double R=287.058, unicode fluidCP=u'Air', int phaseCP=-1) → FlowState¶ FlowState: Returns FlowState at desired altitude in the International Standard Atmosphere.
Parameters: altitude : float
Geopotential altitude [m].
pStag : float, optional
Stagnation (absolute) pressure at sea level [Pa]. Defaults to 101325.
TStag : float, optional
Stagnation (absolute) temperature at sea level [Pa]. Defaults to 101325.
g : float, optional
Acceleration due to gravity [m/s^2]. Assumed to be constant. Defaults to 9.80665.
R : float, optional
Specific gas constant of air [J/Kg/K]. Assumed to be constant, air is assumed to be dry. Defaults to 287.058.
