The truth about Vertical Axis turbines Hugh Piggott's blog

Vertical axis turbines were among the earliest invented but they got replaced by horizontal axis because (like a sailing ship) the wind always comes from one side of the sail and is steady, so the turbine works smoothly and is not buffeted by cyclical stresses. So they stopped making vertical axis for good reasons. Oceanic wind patterns do not seem relevant to the discussion at all. Please ...

Vertical Turbine Pumps Intro to Pumps

Vertical turbine pumps are often staged – that is, designed with more than one impeller. Each additional impeller increases the amount of head the pump can produce while the flow remains unchanged. For example, if a single-stage turbine (one with only one impeller) is designed to produce 1,000 Gallons per Minute (GPM) at 100 Feet Total Dynamic Head (Ft TDH), then adding a second identical ...
