I was reading to my grandchildren from Piping System Fundamentals, their favorite book, and enjoying some family time. We were talking about the pump curve, one of the most important documents dealing with pumped systems. They all had questions about reading the pump curve and understanding why it was so important to know where it is running on the curve. Since they had so many questions, I created this Darcy’s Fable to explain:
Once upon a time was a Raccoon, Possum, and Porcupine lived in the Primeval Woods. Life was hard for the woodland critters, and the past winter was especially long and cold which put everyone in a foul mood. Moreover, food was in short supply and everyone was worried about the future.
As the Raccoon, Possum and Porcupine were sitting by the side of a brook complaining about how hard life was, a beautiful Water Sprite flew by on shimmering wings.
She said to the trio, “I have been listing to your worries and complaints so I thought I would help you out. I will give each one of you a Golden Map. With it, you can find your way to Westwood. There you will find the weather is mild, the food is plentiful and life is much better. Just follow the Golden Map and all will be well.”
Then the Water Sprite flitted off laughing, knowing that her gift would cause misfortune for some of the critters. You see, this sprite was quite mischievous, often tricking people. She then vanished as quickly as she had appeared.
Possum quickly looked at the Golden Map and said, “This looks very simple, I will put it in my backpack and start the journey right away!” However, as the Possum was putting the Golden Map into his backpack, a sudden breeze caught the paper and it fell into the brook where it was swept away.
Possum was undeterred and he said, “No matter, it looked so simple I can easily remember it and find my way to the Westwood,” and he promptly set off.
Then Porcupine looked at the Golden Map and said, “This map must be very important, so I will make sure it is safely in my backpack and I will only take it out if I really need it.” Then he too, immediately set off for Westwood.
After the other two had so quickly gone on their merry way, Raccoon looked at the Golden Map and said, “This must be important, and since Westwood is so very far away I think I will study and learn about this map before starting my journey.”
He then set out to find the Great Owl, the wisest animal in the forest. The Great Owl looked at the Golden Map and after a while, was able to unlock its secrets.
He shared the secrets of the map with Raccoon and showed him the blue line to follow from the Primeval Woods through the Spot of Sweetness and finally going Between the Emerald Peaks (Let’s call it BEP) then your journey to Westwood will be easy.
The Raccoon then set about getting ready and packing for the journey, starting off the following morning. Within two days journey, he made it to Westwood where the winters are mild, the mood bright, and the food is plentiful. Racoon was so thankful he had learned how to read his Golden Map!
But the poor Possum without the aid of the Golden Map went into the “Lowlands of Poor Operation” where there was turbulence, cavitation, and excessive noise. The Possum was so scared in this land that he got totally missed the truck coming down the road he was standing on. Unfortunately he was run over and can still be found by the side of the road.*
Porcupine started his journey, but when he looked at the Golden Map, he could not unlock its secrets. He wandered about aimlessly in the “Land of the Rough Running.” The rocks and the thorny bushes cut his shoes and ripped at his cloths and the noise and thunder keeps him awake at night. He was constantly buying new shoes and wandering around with tattered clothing, a very miserable porcupine.
Suddenly one of my granddaughters exclaimed “Now it get it Pop Pop, for every pump in the plant we should have a pump curve. We should know where each pump is running on its curve and try to operate Between the Emerald Peaks, I mean around the BEP. If we do that we can reduce both its operating cost and maintenance cost.”
Her sister, always the romantic said, “Pop Pop whatever happened to the Raccoon in Westwood?”
I said that he is currently in a long-term relationship with a very attractive girl raccoon and they are looking to have a litter of kits when the time is right. She seemed satisfied with that answer so I chose to leave it at that!
If you'd like to learn more about reading pump curves. Engineered Software Knowledge Base has a couple articles that might help.
Reading a Pump Curve and Pump Curve Landmarks are both very informative.
Let me know what you think of these Darcy's Fables. I have at least one more to share, but I'd like to know what you all think about them. (Read The First Darcy's Fable Here) Leave a comment below or send an email to blogger@eng-software dot com. Thanks for reading!

*(I always like it when a character dies in a story. It keeps them from being too sappy.)
