What is the power delivered, respectively, to the turbine, generators, and end users (a long distance away) from a hydroelectric project operating with a flow rate of 15 m3/s, and 60 m of available potential head (z1-z2). but this time, consider the friction in a penstock that is cast iron and has a diameter of 2 m and delivers the flow to the turbine in a 100 m long section. the turbine and generator efficiencies are 80% and 90% respectively? the transmission lines are 95% efficient. the specific weight of water is γ = 9,800 kg m-2 s-2. assuming that this flow rate is available 24 hrs *365 days a year, how much energy could this hydroelectric dam deliver in a year? if the average household uses 1000 kwh per month and has three people, what size population could this hydroelectric system service?
