Leak rate calculator - LMNO Eng rate is one application where it is widely used. Since a pipe is usually much larger diameter than the hole, V 2 >>V 1 . Since the elevation change Z 2 -Z 1 is typically very small compared to other terms in the Bernoulli equations for a pipe leak application, Z 2 -Z 1 =0.
