This dialog is used to define the points that make up the flow-head curve that is associated with the turbine curve for the associated turbine element. The turbine curve represents the head-discharge relationship of the turbine at its rated speed.

The New button adds a new row to the table; the Delete button removes the currently selected row from the table, and the Report button generates a preformatted report displaying the Head vs. Flow data points for the current turbine curve.
