Lo,
I'm trying to design a turbine or a fan able to "hoove" fruits at the end of a flexible pipeline with a nose of diameter 150/200mm --> 60/78".
My speed should be at least 30 m/s.
I'm really stuck with that and i can't find out where could i find the litterature for that!!
If sombody can help...
