My Finite Element Analysis Professor posed a question to us in lecture and asked that we do a little research on it while at home. We were talking about the Bulk Modulus of Water and Bulk Modulus of Steel. I looked them up and for Water it is 2.2 GPA where as Steel is 160 GPa. He asked, why is it that in Engineering, we model water as an incompressible material whereas we model Steel as compressible when Steel clearly has a much higher resistance to volumetric strain.
I don't deal with water a whole lot in structural engineering but I know that in terms of internal combustion engines, water is always considered to be an incompressible liquid. Can anyone shed some light on this subject? Thanks
