And that means to find the net pressure, we have to have these two values up. So the P hydrostatic minus the P osmotic. So we choose this to be the positive pressure. And this to be the negative pressure. And so 41.3 Mmhg -28 mmhg gives us positive 13.3 Mmhg. The fact that this is positive basically means that the net fluid flow on the arterial end of the capillary will be out of that capillary and into the tissues of our body.
