SECTION-C

Q7. A hydro electric station is designed to operate at a mean head of 210 m and fed by a reservoir having a catchment area of 1000 km² with an annual rainfall of 130 cm of which 75% is available for power generation. The expected load factor is 75%. Allowing a head loss of 5 m and assuming efficiency of turbine and generator to be 0.85 and 0.9, calculate suitable MW rating of the station. Also comment on the type of turbine to be used.
