class sandlersteam.State(*args, **kwargs)[source]

Bases: ThermodynamicState

Thermodynamic state of steam/water.

Molwt: float = 18.01528

Molar weight in g/mol

Pc: Quantity = <Quantity(22.12, 'megapascal')>

Critical pressure

Tc: Quantity = <Quantity(374.15, 'degree_Celsius')>

Critical temperature

description: str = 'Sandler Steam Table State'
get_default_unit(var: str) → Unit[source]

Get the default unit for a given state variable.

Parameters:

var (str) – State variable name (e.g., ‘P’, ‘T’, ‘v’, ‘u’, ‘h’, ‘s’, ‘x’)

Returns:

Default unit for the variable

Return type:

pint.Unit

name: str = 'Sandler-Steam'

Name of the thermodynamic state

resolve() → bool[source]

Resolve all state variables from the two input variables. This is where you’d call your steam tables and calculate everything.

class sandlersteam.UnsaturatedSteamTable(phase: str, table_path: str)[source]

Bases: object

Unsaturated steam table for either superheated vapor (phase=’V’) or subcooled liquid (phase=’L’)

Bilinear(specdict: dict[str, float]) → dict[str, float][source]

General bilinear interpolation dispatcher

PThBilinear(specdict)[source]

Bilinear interpolation given P and another property (v, u, s, h, but not T)

TPBilinear(specdict: dict)[source]

Bilinear interpolation given T and P

TThBilinear(specdict)[source]

Bilinear interpolation given T and another property (v, u, s, h, but not P)

ThThBilinear(specdict: dict[str, float]) → dict[str, float][source]

Bilinear interpolation given two properties from v, u, s, h (not T or P)

minP_at_T(T: float) → float[source]

Minimum pressure at given temperature in C

minT_at_P(P: float) → float[source]

Minimum temperature at given pressure in MPa

minTh_at_P(th: str, P: float) → float[source]

Minimum temperature at given pressure in MPa for specified property th (th = ‘v’, ‘u’, ‘s’, or ‘h’)

minTh_at_T(th: str, T: float) → float[source]

Minimum pressure at given temperature in C for specified property th (th = ‘v’, ‘u’, ‘s’, or ‘h’)

sandlersteam.get_tables()[source]

Get or create the singleton tables instance.
