The name "centre of pressure (COP)" indicates representative pressure will act through this point for a vertical plane inside liquid.

If so, then total thrust= vertical area of the plane x pressure at COP.

But this does not match with the books.

All books say, total force (the thrust)= vertical area of the plane X pressure at centroid.

I do not understand this.
