According to Darcy's formula, the loss of head due to friction in the pipe is (where f = Darcy's coefficient, l = Length of pipe, v = Velocity of liquid in pipe, and d = Diameter of pipe)
[A].
[B].
[C].
[D].
Answer: Option A
Explanation:
No answer description available for this question.
Answer D is correct if the "f" denotes friction coefficient. And Answer: A is correct if "f" denotes the friction factor.

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.

A is right because friction factor is 4times greater than the coefficient of friction and here in question coefficient of friction given so A is right.
