Sizing Pumps in Series with PIPE-FLO & Flow of Fluids

Some system designs require pumps to be operated in series, in which the discharge of one pump eventually leads to the suction of another. This is often done when pipeline and component losses in the system are substantial and it is not feasible (or at least not economical) to achieve the required total head with a single pump.

 

Additionally, series operated pumps may be used to vary the flow through a pipeline, accommodate a wide variation in pumped fluid properties, or compensate for variable downstream conditions. Some examples of systems that utilize pumps in series operation include long pipelines, steam-condensate loops, and primary-secondary chilled water systems. However, one may see boosters pumps installed in a variety of situations. MORE

Engineered Software has partnered with German software company, F.I.R.S.T. GmbH, to be the North American point of contact for all sales of the CONVAL® engineering calculation software program. FULL NEWS RELEASE

 

What this means for PIPE-FLO Users.

The calculations made by CONVAL can be pulled into PIPE-FLO, making valve calculations and selection even easier, more accurate and specific. There are over 20 different calculation modules included in CONVAL and it will export calculation results in multiple formats.

 

The CONVAL program has over 24 different valve manufacturer catalogs, thousands of fluid tables and fluid aliases available in the program in addition to being multi-lingual. More information on the latest release of the CONVAL program can be found on the ESI website. A live demo may be scheduled and a downloadable demo version is also available.

Your Questions Answered

Ask an Engineer

Q.  What is the value of System Resistance Curves (SRC)?

 

 

 

A. System resistance curves can be used to graphically determine flows and pressures in process systems where there is typically one supply pressure or tank, a centrifugal pump, a control valve, and one destination tank or pressure.

 

Using this graphical approach one can visually determine:

  • The flow rate through a pipeline or series of pipelines
  • The flow rate through a pumped systems
  • Determine how multiple pumps operate in a systems
  • Determine the differential pressure across a control valve to restrict flow to a specified valve
  • See how changes to the pump curve can be employed

In this article we'll describe how to create a system resistance curve, and how to best gain information from it.  In future articles we'll discuss means of controlling the flow rate, along with limitations of a system resistance curve, and explore ways to  see how to visualize more complex piping systems.

Ray Hardee Headed to INTERPHEX
esiglobe

We will be sending our certified trainers to Boston, MA at the end of April for an onsite Piping System Training. In early May, we will be headed to Calvert City, KY for an onsite FLO-Master training. We also have scheduled training in Houston, TX, Halifax, NS and Lacey, WA coming up.

 

Ray Hardee will also be presenting at a breakfast sponsored by Crane Co. during the INTERPHEX Trade Show. He will also be available during the show at the Crane booth #2637. The INTERPHEX show is in New York, April 20-22 so make sure to check it out!
