  12. The pressure fall time difference at two pump stations will be: Δt = (tx + t1) - (tx + t2) = t1 - t2 Wave velocity from the point of damage to the first and second pump stations will be V-φ and V+φ , correspondingly. Taking into account notation decribed earlier, time of acoustic signal reaches pump stations will be: t1 = l / (V-φ); and t2 = (L - l) / (V+φ) where I is the distance from the leakange point to the upstream pump station. Then the time difference of pressure drops: Δt = t1-t2 = l / (V-φ) – (L - l) / (V+φ) From that, the distance from the upstream pump station to the leakage point will be: l = (L / 2) * ( 1 - φ / V ) + ( Δt / 2 ) * ( V – φ2/ V) From the above, if distance to the breakdown point is less than half of the distance between two pump stations (l < L/2), then time difference Δt = t1 - t2>0, ifmore than half of the distance (l > L/2), then the time difference is Δt = t1 - t2>0. If time difference is zero, then the breakdown locates at: l = ( L / 2 ) * ( 1 – φ / V ) Theis the fuzzi functional algorithm – i.e. the time difference Δt is calculated and then the rest of calculations performed. There are special programms for fuzzi algorithm calculations, such as fuzzi logic Detav.
