The turbine rated discharge was varied from 300 cfs to 900 cfs to <br /> <br /> <br />define the range of installed capacities to analyze. The turbines were <br /> <br /> <br />assumed to be operable in a range of 40 to 105 percent of the rated discharge. <br /> <br /> <br />The average flow rate was determined by measuring the area under the portion <br /> <br /> <br />of the flow-duration curve that was bounded by the upper and lower flow limits <br /> <br /> <br />of the turbine. <br /> <br />D. <br /> <br />Installed Capacity. /' <br /> <br />1. The installed capacities for the alternative plans were determined <br />with the equation: <br /> <br />kWR = HRQREREC/11.8 <br /> <br />where.. <br /> <br />kWR = Rated capacity at H (Kilowatts) <br />HR = Selected design head (feet) <br />QR = Turbine discharge at H and kW (ds,) <br />EG = Turbine efficiency at H and kW <br />E = Generator eff iciency <br /> <br />2. Basic characteristics of the alternative plans are shown in Table <br /> <br />2. <br /> <br />E. EnerQ:Y. <br /> <br />1. The monthly energy production <br />was calculated with the formula: <br /> <br />available from the alternative plans <br />- <br /> <br />9 <br />
