Velocity Diagram Of Impulse Turbine. The inlet runner is 6 ft above the tail race level and the area and diameter of the runner at inlet are 2 6 sq ft. The relative velocity of the steam leaving the moving blades w 2 is less than the relative velocity of the steam entering the moving blades w 1.
And 3 ft respectively. The inlet runner is 6 ft above the tail race level and the area and diameter of the runner at inlet are 2 6 sq ft. And the available head across the turbine is 150 ft.
The inlet runner is 6 ft above the tail race level and the area and diameter of the runner at inlet are 2 6 sq ft.
Each of the 4 nozzles has an inside diameter 25 40 mm with a coefficient of velocity cv 0 9925. In a vertical francis turbine the runner speed is 380 r p m. The francis turbine is a reaction turbine and it is a combination of impulse and reaction forces and thereby francis turbine is also. Steam turbine impulse and reaction blading r a.
