Application of the dynamics of variable mass systems to the Pelton turbine

This paper deals with an alternative approach to calculate the performance of a Pelton turbine. The discussion begins with an overview on the statement of Newton's second law for variable mass systems. Then the integral form of the Navier-Stokes equation is presented as a special case,which is useful to evaluate the force exerted by the water jet on the turbine buckets. Although the traditional…
