Chapter 2 _ Pelton Turbine _ Fluid Machinery | Turbine | Jet EnginePhysics of Water Turbines Impulse Turbines.. Basic Assumptions The power output of an ideal turbine P T is derived from a simplified BERNOULLI s equation with the following assumptions: no friction no viscosity incompressible medium laminar flow steady flow The only parameters that have to be taken into account are the pressure and velocity differences at inlet and outlet of the turbine. Impulse Turbine Impulse i. The runner of the turbine is driven by the negative acceleration of the periphal flow of the jet, with flow velocity c. If the vane moves towards the jet, the water gains speed; if it pushes a vane moving away, it loses speed. In particular, if the water drives a vane moving at half its speed, then neglecting friction it loses all its velocity and thus its kinetic energy and just dribbles out of the moving vane.
