    1. To reduce velocity/ kinetic energy of water making exit thereby converting kinetic energy to pressure head allowing turbine to be installed above tail pool level.
    2. To create negative suction head.
    3. Provide added head.

    Hiiiiiiiiiiiiiiiiii'

    Dear its reallly a good question that you have asked.well let me explain you that.Generally A draft tube is one important part of a turbine, which is used to transform water into energy.
    * A turbine draft tube is found within the piping system of a turbine.
    * These draft tubes are used in turbines that function in jets, dams, or anywhere else where turbines help do difficult mechanical work.
    * The primary purpose of the draft tube within the turbine is to monitor the influx of water. The turbine has something called a "tail race," which is the lowest portion of a dam or construction project where water pools.
    * The draft tube connects the turbine to this tail race, permitting the turbine to be outside of the water but still have access to the water.
    * With a draft tube, it is possible to maintain the important column of water that keeps the turbine running.
    * The right water level can be maintained despite any potential lack within the amount of material that flows into the machine.
    * In this matter, the tube can help keep the inflow of water into the turbine regular, even if water levels drop, so that the turbine can run properly with the correct amount of pressure maintained.
    * draft tubes have to be installed underneath a dam, plane, or other machinery that is controlled by the work of the turbine.
    * They must be strong enough to withstand the pressure placed on them. If they are installed or repaired after the turbine is already functioning, sometimes they must be placed while other parts are working as well sometimes even while air, gas or water is already flowing through the turbine.
    * The draft tubes thus have to be put into place in the turbine through careful movement along the edge of the equipment.

    Thank You
