Identify the factor that would increase the electrical power output of a hydroelectric plant if its efficiency remains unchanged and all other conditions are kept constant.
(a) Decreasing the density of the water stored in the reservoir
(b) Lengthening the penstock without changing its vertical drop
(c) Increasing the volume flow rate of water through the turbine
(d) Narrowing the penstock outlet so that the water jet velocity rises while the flow rate stays the same
