Percentage of differential pressure lost in a Venturimeter with a tapering of 15° may be about___________________?
Correct answer: B. 10
- A. 1
- B. 10
- C. 25
- D. 50
Explanation
A Venturi meter with a 15° taper has a relatively efficient gradual passage, so its permanent pressure loss is commonly about 10% of the differential pressure. The larger values represent much poorer, more abrupt flow passages.
