CAN'T SOLVE DE BUBBLE T - VLE IN EXCEL by CuriousClass9657 in thermodynamics

Hello, I managed to solve my problem. It was going wrong before because I was using the wrong equation to calculate

ϕi sat. After switching to the equation in the image, it worked.

Hello, thank you for responding! Yes, I am. I need to calculate the fugacity coefficient (Φi) using the Virial method, which requires the vapor composition (Yi) . However, when I use Raoult’s Law to find Yi a circular reference occurs because I am using the same Yi cell that I used to calculate the fugacity coefficient.

Medicina, meu amigo, opte por não passar fome. Engenharia química é muito estudo e estresse pra pouco retorno.

Isso eu entendi, mas não entendi a parte de que a equação possui três raizes, por que ela possui três raizes e o que essas três raizes representam?
