Reduce Pumping Engery Costs
By Using the Optimum Pipe Size
Save Energy -- Evalute several pipe sizes on a lowest life-cycle
cost basis:
According to a U.S. Department of Energy study, about 16%
of a facility's electricity costs result from its pumping systems.
The power consumed to overcome static head can not be reduced, but
savings can be achieved by reducing the power required to overcome
piping system friction.
One way to reduce friction in piping systems is to use plastic
or epoxy-coated steel pipes. This can achieve a greater than 40%
reduction in friction loses. Another way to reduce pumping costs
is to increase the pipe size.
The power required to overcome friction is related to the rate
of flow, the pipe diameter and the overall length of the pipe. The
following will calculate the energy costs based on these three criteria.
The Friction Factor is based on the pipe roughness, pipe diameter
and the Reynolds number (which is based on characteristics such
as fluid density, fluid viscosity and fluid velocity). The Friction
Factor can be obtained from engineering handbooks and is typically
in the range of 0.015 to 0.0225.

pipe diameters.
