Homework Help: Can the Peng-Robinson EOS be solved explicitly for T?

  1. Apr 19, 2013 #1
    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:


    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...
