Momentum
- Definition: A measure of
flow rate times the velocity
of the fluid.
- Useful Equation: F=
m*(Vout - Vin), where m is
mass flow rate, which can
also be expressed as m =
pQ.
- m = pQ. p is density of fluid and Q is the flow rate of the fluid.
- Industrial Application
- In refinery, knowing how large the force a fluid
can exert can determine what brackets and
suitable supports to be used to hold the pipelines.
- In petroleum, knowing the
force fluid exerts in the
pipeline, can be used to
determine the design of the
casing of the pipe.
- Momentum is also a measure of
the sum of forces that fluid
exerts, so knowing the total
force can be used to determine
the equilibrium reaction within a
system.

a system. By equation, as Q is constant, the one
with a larger A will have smaller velocity.
