Design and calculations for the cross-flow turbine

Figure 3. Water flow through the cross-flow turbine. The water strikes the turbine blade rotating the whole turbine wheel. This rotation moves the water jet forward until it has passed over the blade and fallen through the center of the turbine. It has been calculated that 72% of the water jet's power is extracted at this point.
