WebFeb 20, 2011 · That volume is a cylinder with area A2 and length/height L. L is equal to the distance that the water have traveled during t and since its velocity is v2, L = t · v2. Therefore the … WebΔp = p 2 - p 1 (differential pressure) With (4) it's possible to calculate the flow velocity in point 1 - the free flow upstream - if we know the differential pressure difference Δp = p 2 - p 1 and the density of the fluid. It is common to use head instead of pressure. (4) can be modified by dividing with specific weight γ to
