Hi.
We have done some experiments on stretching of DNA strands. We want to expand our report with some physical modelling but we are having some problems understanding surface tension. We have read some introductive book about fuild dynamics and used wiki a lot but we still have problems calculating simple things :(
A simple thing we want to start calculation is how the surface tension act on a cylinder(DNA molecule) with radius 'r' when pulled up of a solution containing only water.. (see figure)
Or more precise we what to calculate the force which we then should be able to compare
with the elastic force of DNA.
Does someone have an idea of what to do.?
Thx.
Peter
