Hi Phil,
For the type of site you describe it might be hard to find something commercially available in axial flow turbines unless you parallel up several units as suggested. Some quick calculations based on your flow and head give a running speed in the range 400-500 rpm with a runner diameter of approximately 0.5-0.6m. I think most axial flow turbines of this size would be custom made for the site...... regards Rob -----Original Message----- From: H2MJD [mailto:[EMAIL PROTECTED] Sent: 25 January 2005 22:52 To: [email protected] Cc: Ron Macleod Subject: Re: [microhydro] Need turbine source Hi....you fells might try contacting www.waterturbine.com .....two of his Nautilus turbines in parallel may suit your site better.......Mark Drabick ----- Original Message ----- From: Carlos Bonifetti To: [email protected] Sent: Tuesday, January 25, 2005 4:18 PM Subject: Re: [microhydro] Need turbine source Phil, Nando: Be careful, a M-Banki turbine for 8 ft head and 800 l/s gives, for 300 mm runner OD, about 1.900 mm runner width, and 206 RPM!.... It's a too big machine, too slow RPM and so very expensive. A runner of greater diameter could be narrower but with less RPM yet. My trial is as I said, an axial flow propeller turbine.
