Hi all,
I am new here, but in my (chemistry) research I have struck upon a problem that one of you might be able to help me with.
I am interested to find an expression for the energy that it would require for an object to expand in a medium of known (dynamic macro-) viscosity. In other words, how much energy is required to push back a volume V (m3) of a medium of viscosity n (Pa*s)? Or, if there is no precooked expression, how to derive this?
Background: the actual problem is situated on the molecular level, and involves the power output of a molecule when changing shape with concommitant volume expansion in a highly viscous environment.
I hope one of you will be able to help me out here, if so thanks a lot!
