1. A two-stage velocity compounded impulse turbine is shown in Figure 2. Some impulse turbines use multiple jets per runner to balance shaft thrust. 3. Newton's second law describes the transfer of energy for impulse turbines . 4. It is a three stage pressure compounded impulse turbine . 5. In 1903 Zoelly developed a multi-stage axial flow impulse turbine in collaboration with Professor Stodola. 6. A friend and colleague of L�on Foucault, Girard was most notable for his work with impulse turbines . 7. De Laval's impulse turbine is simpler, less expensive and does not need to be pressure-proof. 8. Impulse turbines are most efficient for use in cases where the flow is low and the inlet pressure is high.9. In general, impulse turbines are used for high head sites, and reaction turbines are used for low head sites. 10. This is an impulse turbine impacted by burning gases from a cartridge, usually created by igniting a solid propellant similar to gunpowder.
