The energy loss in flow through Venturimeter is less than that through flow nozzle, because in case of a flow nozzle, the ?
Correct answer: C. Sudden expansion of flow in the downstream occurs
- A. Length is shorter
- B. Throat diameter is more
- C. Sudden expansion of flow in the downstream occurs
- D. Distance between the throat and the inlet is more
Explanation
A flow nozzle has a comparatively abrupt discharge and therefore produces a sudden expansion downstream, causing greater eddy and separation losses. A venturimeter uses a gradual diffuser that recovers more pressure.
