help with lee-kesler equation
(OP)
Hello,
I am trying to use the Lee-Kesler equation. As I understand, we need to solve for Z (or Vr) first using the equation once for a simple fluid and then for a reference fluid. This euqation contains Z terms upto 5 th order along with an exponential term. Do we solve for Z by finding the root of the equation? If yes, any idea on how to find the roots of a equation with an exponential term in it?
I need to solve for Z using a computer program, so I cannot use the tables in Polling et al. book. Does any one have a sample code?
Thanks very much in advance.

If you wish to do something more complex do not forget that solving the model (LK or another equation) is only a little step toward the defintion of reliable flash operations which may require a considerably larger effort.

which is a Lee Kesler solver..... is this what is needed? It has a bit of a description with it.
