Answer [A] is correct. Because in the question ' f ' is mentioned as Darcy's coefficient/ Darcy's friction factor which is named after the Frenchmen Henry Darcy. It should not be confused with the friction coefficient/ Fanning friction factor, named after American engineer John Fanning. If ' f ' is given as Fanning friction factor then answer D is correct.

I think answer [D] will be correct.

According to R.S. Khurmi clearly written f=Darcyes coefficient.

Answer D is correct if the "f" denotes friction coefficient. And Answer: A is correct if "f" denotes the friction factor.

Gopal Dey said:   7 years ago
According to me, D is the correct answer.

Hardeep said:   7 years ago
A is correct. Here f is friction factor.
