Kozney-Karman equation for laminar flow Nre <1 where pressure drop is directly proportional to velocity and inversely proportional to the square of dia of particle.
Blake Plummer equation used for turbulent flow Nre >1000 pressure drop is directly proportional to the square of the velocity and inversely proportional to dai of particle.
Combination of Kozney-Karman and Blake Plummer equation is called the Ergun equation.
