3. Results and discussion
3.1. Pressure drop
In literature the pressure drop data were frequently reported
as the Z-factor, which was deBned as the ratioof PPSM=PPEM, where PPSM and PPEM are the pressure
drops for static mixer and that for the empty tube,
respectively (Boss & Czaskiewicz, 1982). These values
are based on the same ReEM, the Reynolds number for
the empty tube, which is deBned as ReEM =Du=. Where
D; u and  are the tube diameter, the mean 7ow velocity,
and the kinematic viscosity, respectively. Fig. 2 depicts
the Z-factor for the present mixer based on the pressure
drop data measured herein. The laminar-turbulent transition
could be located at approximately of Re=150, which
correlates with Paul and Muschelknautz (1982). Such an
observation suggests that the static mixer could initiate
early transition to turbulence compared with the case of
the empty tube (2,100–4,000).

以下翻译请楼主审阅，其中有几处打字有点问题（如7ow），只能尽力理解翻译

3.1 压力降
In literature the pressure drop data were frequently reported as the Z-factor, which was deBned as the ratioof PPSM=PPEM, where PPSM and PPEM are the pressure drops for static mixer and that for the empty tube, respectively (Boss & Czaskiewicz, 1982). 在文献中，压力降数据常常被报道为Z因子，它被定义为PPSM＝PPEM的比率，这里PPSM和PPEM分别为静态混合器的压力降和空管的压力降（Boss&Czaskiewicz，1982）。These values are based on the same ReEM, the Reynolds number for the empty tube, which is deBned as ReEM =Du=. Where D; u and  are the tube diameter, the mean 7ow velocity, and the kinematic viscosity, respectively. 这些值都基于相同的ReEM，即空管的雷诺数，它被定义为ReEM＝Du=。这里，D,u,和分别为管的直径，平均7ow速度和运动粘度。
