Question
Q-89A turbine runner has an exit velocity of 10 m/sec. The loss due to friction
and other causes in the draft tube should not exceed 2.0 m. What maximum
height of setting will you recommend for the turbine if the cavitation is to be
avoided. The velocity of water at out let of draft tube is 2 m/sec and cavitation
commences when the pressure is 2.5 m of water absolute.
