Abstract: Field measurement of discharge has been performed for a Bulb turbine based on current-method in this paper. Winter-Kennedy coefficients of this machine are calibrated based on the test results of integrated discharge and measured flow differential pressure between bulb head and stay cone. Calibration shows that discharge and flow differential pressure of the test machine follow the power model very well. The uncertainty of discharge estimation by Winter-Kennedy method for Bulb turbine is discussed finally.
