This energy is spent giving the flu

This energy is spent giving the fluid a velocity of v. We can express this energy of the moving fluid in terms of its kinetic energy (KE) as follows:
KE=mv2

Since the two energies are the same,
PV=mv2

However , by definition, mass m is equal to volume V time's density p, so we can replace mass in the equation with V x p to obtain the following:
PV = V pv2 2

If we cancel the volume term from both sides of the equation, we obtain
AP = Pv2

Then, solving for velocity and taking the square root of both sides of the equation, we obtain the general equation for the velocity of any fluid in a pipe:

This velocity is expressed in terms of the pressure differential and density of the fluid.

Volumetric flow is defined as the volume of fluid that passes a given point in a pipe per unit of time. This is expressed as follows:
Q=Av

where
Q = the vulometric flow
A = the cross-sectional area of the flow carrier (e.g., pipe)
v = the fluid's velocity

We can also define mass flow rate (W) as the mass or weight flowing per unit time. Typical units are pounds per hour. This is related to the volumetric flow by the following:
