Q2.1 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 outlet of draft tube is 2 m/sec and cavitation commences when the pressure is 2.5m of water absolute.
