Dear Sai Gembali

Please take a look at the following reference:

White, Frank M., and Isla Corfield. Viscous fluid flow. Vol. 3. New York: McGraw-Hill, 2006.

There too many videos about this topic and Give you enough information about it starting from NSE to the final Equation.

Dear Sai Gembali

The book by Versteeg and Malalasekera ( https://www.amazon.com/Introduction-Computational-Fluid-Dynamics-Finite/dp/0131274988/ref=sr_1_1?crid=PBBZV68VDRWN&keywords=versteeg+and+malalasekera&qid=1566631578&s=gateway&sprefix=versteeg%2Caps%2C410&sr=8-1 ) is a good place to start. You should find what you are looking for in chapters 2 and 3.

All the best

One can start with full Navier-Stokes equations in the desired coordinate system. Assumptions for each case can simplify the equations.

Hi

This file have good information about turbulent and laminar flow equations.
