[for the tl;dr peeps: is there any point plotting a force distribution when I already have a pressure distribution, aren't they essentially the same thing?]

I've been doing wind tunnel experiments on structures for my final year engineering project, my supervisor (who I have a feeling knows less about the topic than me, which isn't much) has asked me to come up with contour plots for the forces on a model, and I'm wondering how to go about it, and if it is even possible.

What I have at the moment is a bunch of pressure values at various locations and from this contour plots of the Pressure Coefficient, C

_{p}= (p - p

_{o})/(0.5ρV

^{2}) - it seems trivial to convert these values to forces for some corresponding area - simply multiply C

_{p}by 0.5ρV

^{2}L

^{2}- but this will be a force value for a specific area, and seems pointless to plot this when we already have the Cp values with are a dimensionless representation of pressure - a force per unit area.

Any thoughts are appreciated... from what I can tell "plotting the force distribution" seems like a fairly pointless exercise when I already have the pressure distribution, but I'm keen to hear some opinions.

Thanks in advance for any help!
