6.9 One stage of an impulse turbine consists of a converging nozzle and onering of moving blades. The nozzle angles are 22° and the blade angles are35°. The velocity of steam at the exit from the nozzle is 650 m/s. If therelative velocity of steam to the blades is reduced by 14% in passingthrough the blade ring, find the diagram efficiency and the end thrust on theshaft when the blade ring develops 1650kW.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

6.9 One stage of an impulse turbine consists of a converging nozzle and one
ring of moving blades. The nozzle angles are 22° and the blade angles are
35°. The velocity of steam at the exit from the nozzle is 650 m/s. If the
relative velocity of steam to the blades is reduced by 14% in passing
through the blade ring, find the diagram efficiency and the end thrust on the
shaft when the blade ring develops 1650kW.
