Dear all,

I have a question regarding hydrostatic pressure difference in "Simulation
with induced pressure difference " (http://www.ks.uiuc.edu/
Training/SumSchool/materials/sources/tutorials/04-
nanotubes-tutorial/html/node6.html).

For delta_P=nf/A, the A here is the volume of the system with f, or the
volume of whole simulation box?
If I have vacuum layer in my simulation, does the volume include the vacuum
layer?
Thanks in advance!

Houyang
