Question

Carmen-Kozney equation has been derived using which of the following equation?

(a) Cole brook white equation

(b) Bernoulli equation

(c) Darcy Weisbach equation

(d) Swamee jain equation

I had been asked this question in an internship interview.

Query is from Filtration Hydraulics in section Filtration of Environmental Engineering

Answer 1

Right choice is (c) Darcy Weisbach equation

Explanation: Carmen-Kozney equation has been derived using Darcy Weisbach equation which is given by h = f*l*v^2/(g*D) Where h is the head loss, D is the diameter of pipe, v is the velocity of the particle and f is the dimensionless friction factor.
