|
Python |
kh(T:np.ndarray,gas:str,heavywater:bool=False)->Union[np.ndarray,float]: |
Computes the Henry constant kH in MPa for a given temperature T in water or heavy water.
Arguments:
|
T(:) |
Temperature in K. |
|||
|
gas |
Gas. |
|||
|
heavywater |
Flag if D2O (1) is used or H2O (0). |
|||
|
k(:) |
Henry constant in MPa. |
k is filled with NaN if gas is not found.
Fortran:
use iapws
real(dp) :: T(1), k(1)
T(1) = 25.0_dp + 273.15_dp
call kh(T, "O2", 0, k)
C:
#include "iapws.h"
double T = 25.0 + 273.15;
char *gas = "O2";
double k;
iapws_g704_kh(&T, gas, 0, &k, strlen(gas), 1);
Python:
import numpy as np
import pyiapws
T = np.asarray([25.0])
k = pyiapws.kh(T+273.15, "O2", False)
