Value of a System Resistance Curve (Part 2)

This article is a continuation of the Ask an Engineer article from the April Issue, dealing with the System Resistance Curve. As discussed in the last installment we saw how a system curve was created by calculating the head loss for each pipeline in the system under a variety of flow rates. Once this is done then you can sum the head losses for the pipelines in series for a variety of flow rates.

 

Then by superimposing the pump curve on the system curve, the flow rate through the system occurs at the intersection of the pump curve and system curve. A centrifugal pump will only operate on its pump curve; this makes it helpful in understanding the operation of the pump in the piping system. . MORE

System Assessment & Optimization TrainingPiping System Assessment & Optimization Training

 

The Fall Training schedules have been Announced. Thirteen classes over four months looks to be a bustling fall training season!

 

For a look at the classes in your area, you'll need to look at each class schedule individually.

 

Among the classes on the schedule this fall is the all new, Piping System Assessment & Optimization course based on the new ASME standard Energy Assessment for Pumping Systems Standard (ASME EA-2-2009) worth 24 Professional Development Hours.

 

We also have a Centrifugal Pump Webinar coming up on July 8th for only $95. Your registration includes 2 PDH or 0.2 CEU and a copy of the program for you to retain.

 

If the Fall Schedule doesn't have a location near you or you are interested in hosting an onsite seminar, call 1-360-412-0702 or email us at training@eng-software.com and we will be happy to discuss your options.

Ask an Engineer

Q. What is static head and how is the static head calculated for a system that contains a fluid at different temperatures?

 

 

 

A. The static head of a system is that portion of the pump's Total Head that must be added to the fluid before a single drop of fluid will move in the system. It is the amount of energy, or head, which is used to overcome the pressure and elevation differences in the piping system. It can be calculated using the following equations:

 

Static Head = ∆ Elevation Head + ∆ Pressure Head

 

∆ Elevation Head = Elevation of Discharge Tank's Liquid Surface – Elevation of Supply Tank's Liquid Surface

 

∆ Pressure Head = (Discharge Tank's Surface Pressure – Supply Tank's Surface Pressure) × (144/ρ)
