6.2 Forebay and Surge Tanks: importance, general arrangement, condition of their application, hydraulic design
Design a forebay for a power plant with a design discharge of 14 m³/s. The system uses two penstock pipes, each with a length of 500 m and diameter of 2 m, to convey water. Assume a detention time of 3 minutes and a flow velocity of 0.2 m/s in the forebay. Additionally, design an appropriate spillway length for the forebay. [8]
