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? |
|
What are the
minimum system requirements to run the Flow of Fluids
program? |
|
|
|
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. |

|
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. |
