The Bell and Gossett System Syzer® – a few other uses
|Printer Friendly (PDF)
Last week we used the ITT Bell and Gossett system syzer to select a pipe size for 800 GPM. We used the wheel and the electronic version. Today, let’s expand the selection to include a fluid other than water. To use fluids other than water you must use the electronic version. There were two solutions from last week’s example using water:
Now let’s change the fluid in our example from water to 50% Ethylene Glycol at 40° F. Start by clicking on the “fluid” at the top of the page and remove the 60° F water selection to allow changes. Select ethylene glycol and enter the 40° F and 50% options. Notice the viscosity jumps to 6.65 and the specific gravity is 1.07. We can expect an increase in friction loss with this new fluid.
Select “OK” and we see 6” pipe with a pressure drop of 5.04 feet/100 feet and 8” pipe at 1.33 feet/100 feet. This may make us decide to change from the 6” pipe to the 8” pipe to keep the pump horsepower lower.
Next week we will use this information for other correction factors.
