and (c) 2 m3/sec for 6 months: (i) If the site is developed as a run-of-river type of plant, without storage, determine the standby capacity to be provided. Assume that overall efficiency of the plant is 85%. (ii) If a reservoir is arranged upstream, will any standby unit be necessary, and what is the excess power?

Question
A factory is located near a waterfall where
the usable head for power generation is 26
m. The factory requires continuous power
of 500 kW throughout the year. The river
flow in a year is (a) 6 m3/sec for 6 months,
and (c) 2 m3/sec for 6 months: (i) If the site
is developed as a run-of-river type of plant,
without storage, determine the standby
capacity to be provided. Assume that
overall efficiency of the plant is 85%. (ii) If a
reservoir is arranged upstream, will any
standby unit be necessary, and what is the
excess power?
