Here is a list of the most frequently asked questions
about the Flow of Fluids Premium program.
Why should I use Flow of Fluids Premium when my
spreadsheet provides me with the results I need?
What is the maximum number of pipelines Flow of Fluids
Premium can handle, and what is considered a pipeline?
What pipe materials does Flow of Fluids Premium support?
Can I create my own pipe size tables, or modify the
tables shipped with the software?
What valves and fittings does the program support?
What if the supplied table doesn't have the valves and
fittings I use?
What
fluids does the program support?
Can
I model pumps in the piping system?
How many manufacturers support Flow of Fluids Premium by
distributing their pump catalogs for use with the
program?
How do I model a pump if a manufacturer's electronic
pump catalog is not available?
Can Flow of Fluids Premium handle compressible gases
as well as liquids?
Why should I use Flow of Fluids Premium when my Excel
spreadsheet provides me with the results I need?
Excel spreadsheets only calculate the head loss in a
single pipeline for a given flow rate.
Flow of Fluids Premium also calculates the head loss
in a single pipeline, in addition it:
-
Calculates the flow rates and pressures in the
entire piping system by performing a full hydraulic
network analysis.
-
Selects
centrifugal pumps from manufacturers' supplied
electronic pump catalogs.
-
Inserts
the pumps and control valves into the piping system
model, showing how the entire piping system
operates.
-
Considers
alternate operating conditions and shows you how the
system operates.
Flow of Fluids Premium provides you with a total
system view instead of a head loss calculation for a
single pipeline.

What is the maximum number of pipelines Flow of Fluids
Premium can handle, and what is considered a pipeline?
Flow of Fluids Premium has a program limit of 25
pipelines. A pipeline is between two junctions and
consists of one pipe diameter including all the valves
and fittings. For example if you have a system with one
tank feeding two destination tanks, the system consists
of 4 pipelines. There is one pipeline from the supply
tank to the pump suction, a pipeline from the pump
discharge to a junction, and two pipelines each going
from the junction to each destination tank.

What pipe materials does Flow of Fluids Premium support?
Flow of Fluids Premium uses engineering data tables
to look up the pipe data needed to perform the pressure
drop calculations. You select the pipe material, and
schedule or wall thickness, and the program presents the
available nominal sizes. The program looks up the inside
diameter and uses that value in the pressure drop
calculations. The program comes with a variety of pipe
size tables based on published pipe standards.

Can I create my own pipe size tables, or modify the
tables shipped with the software?
Yes. Using the supplied Table Manager program you can
modify the pipe tables shipped with the program or
create your own custom pipe size tables for specialty
pipe material.
Back To Top
What valves and fittings does the program support?
The program looks up valve and fitting information in
a valve table shipped with the program. The table
contains all the valves and fittings found in the Crane
Technical Paper 410. Specialty valve and fitting tables
are available from selected manufacturers.

What if the supplied table doesn't have the valves and
fittings I use?
You can insert any valve or fitting into the model by
entering either the K value, Cv value, or the
differential pressure for a given flow rate. In
addition, using the Table Manager program you can even
create your own custom valve and fitting tables.

What
fluids does the program support?
Flow of Fluids Premium looks up the fluid information
in engineering data tables. Flow of Fluids Premium
comes with a fluid compilation of 250+ process fluids
for use with the program. You can also add custom fluids
in your projects by entering the fluid properties, this
way you can model any Newtonian fluid (both liquids and
gases).

Can I
model pumps in the piping system?
Yes. The program supports both centrifugal and
positive displacement pumps. You can use the program to
select pumps directly from manufacturers' supplied
electronic pump catalogs.

How many manufacturers support Flow of Fluids Premium by
distributing their pump catalogs for use with the
program?
The current list of supporting pump manufacturers
distributing their electronic pump catalogs is available
at
http://www.eng-software.com/pml/. Many of the
manufacturers allow you to download them directly from
this Website.

How do I model a pump if a manufacturer's electronic
pump catalog is not available?
You can model any centrifugal pump by manually
entering pump performance data from a paper pump curve
in the piping system model.
