What are these 5 methods used to find friction drop across a duct?
1. Dukler's Homogeneous method

2. Dukler's constant slip method
3. Lockhart Martinelli method
4. Beggs and Brill method
5. Isothermal compressible flow method.

What is the use of these methods, what are their assumptions, equations and how do each differ from other?

I found these method to calculate the friction drop but I am unaware how exactly do these methods calculate friction drop?
