A firm wants to build mini hydro power plant and pumped storage hydroelectricity system. Flowrate is assume 100 l/s. The pipes are build from Carbon Steel (Cement-lined). a) Calculate the total pump head for the given system. For this system, static head is 15 m, and pump is 2 meter above the suction side. - 17 m- - 5 m - - 4 m Steel pipe NB 250 mm Pump Info water temp 20°C -17.
