Choose an option
-
ARuns purely by the impulse of water only
-
BRuns purely by the weight of water only
-
CRuns partly by the weight of water and partly by the impulse of water
-
DRuns only by reaction of water jets
Answer
Correct Answer: Runs partly by the weight of water and partly by the impulse of water
Explanation
Background
- Water enters a breast wheel near the level of the wheel axis (breast height).
Operating principleThe wheel develops torque from both the weight of water contained in the buckets and the impulse of the incoming stream.
Final AnswerPartly by weight and partly by impulse.
