By Bernoulli's law, if potential energy is constant, the work done, given by pV, where p is the pressure, V is the change in volume, is equal to the change in kinetic energy, 1/2mv^2.(adsbygoogle = window.adsbygoogle || []).push({});

Does that mean that the flow rate of the liquid is proportionate to the root of the pressure applied??

If it is so, why is it that by Poiseuille's law of flow, E = (pi)r4pt/8Vl,

E is the viscosity of the flowing liquid, t is the time for which the liquid flows, V is the volume of liquid which flows in that time, r is the radius of the pipe, and l is the length of the pipe,

that the rate of flow is proportionate to the pressure applied??
