density

typhon.physics.density(p, T, R=287.0570048852906)[source]

Calculates gas density by ideal gas law.

\[\rho = \frac{p}{R \cdot T}\]

Parameters

p (float or ndarray) – Pressure [Pa.]
T (float or ndarray) – Temperature [K]. If type of T and p is ndarray, size must match p.
R (float) – Gas constant [J K^-1 kg^-1]. Default is gas constant for dry air.

Returns

Density [kg/m**3].

Return type

float or ndarray
