According to Kennedy's silt theory , the critical velocity is directly proportional to depth of flow _____________________?
Correct answer: D. D0.64
- A. D0.67
- B. D0.65
- C. D0.66
- D. D0.64
Explanation
Kennedy's silt theory gives critical velocity as proportional to D^0.64, where D is the flow depth. The exponent 0.64 is therefore the distinguishing value among the choices.
