ESSOM COMPANY LIMITED Section 2: Theory SECTION 2: THEORY General Theory A water turbine is a hydraulic machine for transforming fluid energy into useful mechanical work at a rotating shaft. The power engineer is concerned with the generation of this shaft work in a hydro power plant from the stored mechanical potential energy in a body of water behind a dam.

ESSOM COMPANY LIMITED Section 2: Theory ▪ Friction Head When a liquid flows from one point to another, part of energy or head of liquid flow is lost due to friction between the liquid and the pipe wall or the flow channel wall as well as the interaction of the liquid molecules. The resulting head loss is called Friction Head.

ESSOM COMPANY LIMITED Part 3: Experiment TEST RESULTS - TURBINE PERFORMANCE CURVES Test results are commonly expressed in the form of curves plotting on graph paper. They are known as “Turbine Performance Curves or Characteristic Curves”. In plotting the curves, basic characteristics of turbine performances taken directly from the recording data and data of calculated results are used.
