CONCLUSION

 
The major aim of this study was to obtain consistent results . To introduce a pump is not as easy as it seems. Indeed, characteristics pump are numerous (loop velocity, number of stages, different diameters). Moreover, we did not know at all TACITE Code and to be able to use it needs time.

But finally, our results are good and may represent the reality. "May" because reality characteristics

To conclude this study , a lot of interessant results are available  with TACITE Code and to exploit them can provide  a lot of work.
