Hydropower Engineering past question

The mean monthly flow of a river at the headworks site of a ROR hydropower project is as follows [table]. Other data: net available head = 150 m; efficiency of turbine = 95%; efficiencies of generator = 97%; fixed cost = NRs. 10,00,00,00,000; variable cost (present worth value) = NRs. 1,50,000/kW; energy price = NRs. 10 per unit; interest rate = 10%; economic life of the project = 45 years. Estimate the best installed capacity, firm energy, secondary energy, total energy, and power factor of the project. [10]
