Question

An inward flow reaction turbine has an external diameter of 1 m
and its breadth at inlet is 260 mm. If the velocity of flow at inlet is 2
m/s, find weight of water passing through the turbine per second.
Assume 11 per cent of the area of flow is blocked by blade
thickness. If the speed of the runner is 210 r.p.m. and guide blades
make an angle of 10° to the wheel tangent, draw
the inlet velocity triangle and find:
(i) The runner vane angle at inlet,
(ii) The velocity of wheel at inlet,
(iii) The absolute velocity of water leaving the guide vanes, and
(iv) The relative velocity of water entering the runner blade.​

Answer 1

Answer:

An inward flow reaction turbine has an external diameter of 1 m

and its breadth at inlet is 260 mm. If the velocity of flow at inlet is 2

m/s, find weight of water passing through the turbine per second.

Assume 11 per cent of the area of flow is blocked by blade

thickness. If the speed of the runner is 210 r.p.m. and guide blades

make an angle of 10° to the wheel tangent, draw

the inlet velocity triangle and find:

(i) The runner vane angle at inlet,

(ii) The velocity of wheel at inlet,

(iii) The absolute velocity of water leaving the guide vanes, and

(iv) The relative velocity of water entering the runner blade.
