Hello,

I would like to report an error in the calculation in the iapws97.

It seems like the function iapws.iapws97.IAPWS97_Ph does not return the correct "x" value when entering with p = 18 MPa, h = (h_l_sat + h_s_sat)*0.5

Thanks for report, a elusive bug in a tiny region near critical zone between region 3 and 4. Check now if it works for you
