A Francis turbine may be operated over a range of flows approximately 40 to 105% of rated discharge. Below 40% rated discharge, there can be an area of operation where vibration and/or power surges occur. The upper limit generally corresponds to the generator rating. The approximate head range for operation is from 65% to 125% of design head.
