On the Rotor Stator Interaction Effects of Low Specific Speed Francis Turbines

<div>The mean sector pressure from the pressure sensors as percentage of specific energy. The angular size of each sector was 0.5°, with 720 sectors in total. The mean sector pressure was calculated from 600 full revolutions.</div>
