What is draft tube?
Draft Tube: The draft tube is a pipe gradually increasing area used for discharging water from the exit of a reaction turbine. It is an integral part of mixed and axial flow turbine. Because of the draft tube, it is possible to have the pressure at runner outlet much below the atmospheric pressure.
Efficiency of a draft tube is defined as the ratio of net gain in pressure head to the velocity head at entrance of draft tube.
