Dear Friends,

Welcome to a new academic year, and hope you had a fantastic break.

I am happy to announce that a release of a new website for the online courses of mine, see link www.science4fluids.com. The website would let you find the relevant contents more easily.
Currently I am focused on the courses for ‘Fluids made-easy’, in which I included the talks on fluid mechanics and fluid dynamics, with an aim to provide simple, clear and understandable materials for fluid mechanics and dynamics, so for better understanding of the flow phenomena. And I will update the talks consistently, so please stay connected and tuned.

Following is my recent video talk:
How we can derive Bernoulli's equation, Part 2: the derivation based on streamline equations
