            摘要:

            介绍了柔性风管压力损失的理论模型。通过实验研究了两种常用柔性风管在全伸展状态时的压力损失,得出了它们的绝对粗糙度值。给出了柔性风管完全展开时的阻力计算图,可供工程设计时使用。

            Abstract:

            Presents the theoretical model of pressure drop for flexible duct. Studies experimentally the pressure drop of two common kinds of flexible duct in fully extended state and obtains their absolute roughness. Represents the friction calculation chart of the duct for graphic calculation during project design.
