Water

Provides fluid properties for liquid water between 0-100 C.

Example:

from scp.water import Water

if __name__ == "__main__":
    water = Water()
    temp = 10  # Celsius
    print(water.viscosity(temp))

class scp.water.Water

Bases: BaseFluid

conductivity(temp: float) → float

Returns the fluid thermal conductivity for this derived fluid.

Thermal conductivity equation from linear least-squares fit to data in CRC Handbook (op.cit.), page E-11

@param temp: Fluid temperature, in degrees Celsius @return: Thermal conductivity, in [W/m-K]

density(temp: float) → float

Returns the fluid density for this derived fluid.

Density eq. for water at 1 atm., from CRC Handbook of Chem. & Phys., 61st Edition (1980-1981), p. F-6.

@param temp: Fluid temperature, in degrees Celsius @return: Density, in [kg/m3]

property fluid_name: str

freeze_point(_=None) → float

Returns the freezing point temperature of water

@param _: Unused variable @return Freezing point temperature, in Celsius

specific_heat(temp: float) → float

Returns the fluid specific heat.

Specific heat of water at 1 atmosphere, 0 to 100 C. Equation from linear least-squares regression of data from CRC Handbook (op.cit.) page D-174

@param temp: Fluid temperature, in degrees Celsius @return: Specific heat, in [J/kg-K]

viscosity(temp: float) → float

Returns the viscosity of water.

@param temp: Fluid temperature, in degrees Celsius @return: The dynamic viscosity of water in [Pa-s]
