本文对四个直径比为1的光滑三通的损失系数和功率损失系数进行了实验测定。在整个测试过程中，分流前或分流后的雷诺数在10\u5-2x10\u5的范围内。连接边缘处的壁的曲率半径从零到直管直径的一半不等。给出了各种流态下的损失系数和功率损失系数的经验公式，这些公式与实验结果吻合较好。还给出了盲端三通损耗系数的经验公式。与以往研究的实验结果的比较表明，所提出的公式可以用来可靠地估计在T形件的能量损失。
The loss coefficients and the power-loss coefficients for four smooth tees with diameter ratio of unity were determined experimentally for each of all configurations of flow through tees. Throughout the test the Reynolds number before the division or after the combination of flow was within the range of 10\u5–2x10\u5. The radius of curvature of the wall at the joining edge ranged from zero up to half the diameter of the straight pipe. Empirical formulas for loss coefficients and those for power-loss coefficients which are in good agreement with experiments were presented for each configuration of flow. Empirical formulas for loss coefficients for dead end tees were also given. The comparison of the proposed formulas with the experimental results of the previous investigations showed that the proposed formulas can be used to reliably estimate the energy losses at tees.
