  • b)
    1.4 m and 2.04 m respectively
  • c)
    1.4 m and 0.2 m respectively
  • d)
    14.13 m and 0.2 m respectively
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
An outward radial flow impulse turbine has nozzles with a total area ...
Refer to Fig. in question for nomenclature and vector diagrams.
Analysis at inlet:
Work done (or head utilized) per unit of weight of water
= 9810 × 0.03 × 41.96 = 12350 W
= 12.35 kW
(ii) Power lost due to friction at the bearings = water power − brake power
= 12.35 − 11.75 = 0.60 kW If hf is the head loss in bearing,
then 0.60 × 103
= 9810 × 0.03 × hf ;
hf ≈ 2.04 m
