Great work

[@rahmatsunarya]

Thank you my friend

[@essidabouhligha3914]

Good job, I will try do the same example but with different procedure to solve Rachford Rice Equation.

[@rahmatsunarya]

@@essidabouhligha3914 Perfect. Hope I can see your work

[@rahmatsunarya]

Really? Could I get your work at [e-mail], sir? Thank you much Sir 🙏🏻🙏🏻

[@essidabouhligha3914]

I have did the example with different procedure. and I got the same results.

[@rahmatsunarya]

Perfect. Could I get the result? Maybe send to my email?

[@essidabouhligha3914]

@@rahmatsunarya Okay. Give me your email
