Hi all: As we know, all liquids have different compressibility factors, Z. I think Ed K said (rightly so) it wasn't worth arguing about - we don't really need to be concerned about the compressibilities of liquids at standard temperature and pressure. However, the compressibility factor, which can be critical in engineering measurements/predictions, are definitely important when T and P increase. Anyhow, unless we are doing live steam, enjoy modeling and don't worry too much about compressibility (unless one is a worrier - then google it or get some engineering/physics books on changes of state)! regards, Rance Velapoldi (Tranby, Norway)
