The water way from a weir is determined by using Lacey's wetted perimeter i.e. P=_______(Q)1/2 ?
Correct answer: C. 4.75
- A. 3.50
- B. 3.75
- C. 4.75
- D. 5.75
Explanation
For Lacey's regime theory, the wetted perimeter is commonly written as P = 4.75√Q when the silt factor is taken as unity. Thus, the coefficient used in this question is 4.75.
