W1 is the Velocity of fluid entering tangent to blade(relative velocity)U1 is the Velocity of bladeV1 is the absolute VelocityW1U1V1V1=V1=W1+U1Blade AnalysisAs the water coming with relative velocity W1 it should have the same velocity after striking the blade if there are no loses|W1|=|W2|To get the velocity after striking

V2=W2cos+U2

Blade AnalysisNow by using the Moment and Momentum equation we obtained a relation for Work of shaft of our turbine design.

Conditions For working of DesignIt is necessary that that the value of Absolute velocity of fluid entering the blade is greater than the value of velocity of blade other wise this design will not behave as a work output device.
