design of pumped water storage scheme for abandoned reservoirs
Solved In a pumped-storage scheme, water is supplied to a
In a pumped - storage scheme, water is supplied to a single turbine through a 2 0 0 m long, 2 m diameter penstock line. The power plant uses two centrifugal pumps to pump water back to the upper reservoir ( headrace or the dam), using the same penstock pipeline. Basic data are as follows: Pumps two in number, rated capacity 6 M W ...
