WebFeb 20, 2011 · 3. (blood) pressure = F/area = m*a/area = m*v / area*second. 1) this area is the whole area meeting the blood inside the vessel. 2) which is different from the areas above (that is the … WebThe answer is right. Intuitively, if you want to double the velocity of the escaping air, you need to quadruple the pressure. The reason is that pressure (force) is momentum (of the air) per unit time, and if the velocity doubles, you're doubling the momentum of each parcel of air, and you're doubling the number of parcels of air. – Mike ...
