AI Thread Summary
The discussion revolves around the ability to solve the Peng-Robinson equation of state (EOS) explicitly for temperature (T). Initially, the poster expressed uncertainty about the feasibility of isolating T in the equation. After some attempts, they found a method by substituting T with t2 to eliminate the square root and then solving the resulting quadratic equation. The poster thanked another user, gneill, for their assistance in reaching a solution. This exchange highlights the collaborative nature of problem-solving in engineering contexts.

I'm not sure if this is the right forum to ask this question, but it arose as part of an engineering problem, so here goes.

The Peng-Robinson EOS is as follows:

P=\frac{RT}{v-b}-\frac{a[1+k(1-\sqrt{\frac{T}{T_{c}}}]^{2}}{v(v+b)+b(v-b)}

I'm just wondering if this equation can be solved explicity for T. I tried but I had no luck.

Presumably T is a positive value. Replace T with t2. That'll let you pull it out of the square root. Solve the resulting quadratic for t...
 
Okay, I figured it out. Thank you gneill!
