BWRS 气体状态方程代码

BWRS气体状态方程是一种用于计算气体物质状态的方程，它是根据Benedict-Webb-Rubin-Starling公式（BWRS公式）推导得出的。该方程可以用于计算气体的压力、体积和温度之间的关系。

以下是一个示例的BWRS气体状态方程的代码实现：

def bwrs_equation(pressure, volume, temperature, critical_pressure, critical_volume, acentric_factor):
    R = 8.314  # 气体常数
    a = 0.45724 * (R ** 2 * critical_temperature ** 2) / critical_pressure
    b = 0.07780 * R * critical_temperature / critical_pressure

    alpha = (1 + (0.37464 + 1.54226 * acentric_factor - 0.26992 * acentric_factor ** 2) * (1 - (temperature / critical_temperature) ** 0.5)) ** 2
    a_alpha = a * alpha
    b_alpha = b

    Z = pressure * volume / (R * temperature)
    Zc = critical_pressure * critical_volume / (R * critical_temperature)

    A = a_alpha * pressure / (R ** 2 * temperature ** 2)
    B = b_alpha * pressure / (R * temperature)

    f1 = Z ** 3 - (1 - B) * Z ** 2 + (A - 2 * B - 3 * B ** 2) * Z - (A * B＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
