OPTIMIZATION OF PENSTOCK GEOMETRIC DESIGN ON HYDROPOWER SYSTEM

Penstock is an important component in hydropower system. The function of this component is to accommodate the water flow from the forebay to the turbine. The existences of penstock allow for increased flow rate is influenced by the geometric size of the pipe. Increased speed is sparking potential...
