Does anyone know of a tube turbine manufacturer that has an appropriate micro-hydro turbine suitable for the following parameters?
.09 m3/s @ 4 m head average
Flow varies from .04 to .14 m3/s (75% of the time it is at or above .08 m3/s).
Head fluctuates between 3 m and 5 m depending on tides.
I have a site that could accept 17 turbines to handle the flows mentioned above. I would like to grid tie these turbines. Voltage on site is 440v/60hz.
