I have a surface S in discrete from, i.g., i only have [x,y,z]data, but not a function. This surface is under air pressure P, which is perpendicular to the surface everywhere with a constant value. I want to know the force vector F on the surface caused by the air pressure, i.e. integrate P over S in discrete form. Could anybody help? How about surface S is in polar format? Thanks a lot.
