Hello all. I am a member of a volunteer fire department. I am finally getting around to attending "Introduction to Fire Department Pumpers" this weekend. Looking forward to it!

Bill, need to know what size opening you are flowing from to determine the gpm.

Need some help....one of my operators through a scenario at us the other night and I need some help.  Im trying to calculate the amount of water moved in one of two ways.  First:  5" LDH connected to a 4" discharge on the pump at 125 psi, with a 2000 gpm pump.  The second scenario would be (3) 2 1/2", 25' long lengths of hose into a water appliance which siameses into a 5" discharge.  Same engine pressure on each.  How can I figure out the amount of water moving in each scenario.

So my Chief asks if I could take TP & Engine for pump test drafting.. Suuure no problem I'll take the day off. So he says ok Erick, testing is the 14th. Make sure to clear that day.... Clear the day I say? Yep, gonna take about 6 hours... (poker face).... Seriously? 

 

So make sure before you jump to volunteer your services, you know what your getting into! But I did hear that a pump operator can learn a lot from these guys.

Hey Jeff, After being active for 35 yrs. on a dept. in Vermont 20 miles south of the Canadian border, we run wet. I believe wet is better, for the reason being that if your station is at at least 55 degrees your pump has a lessor chance of freezing up over a short period on time than a dry pump.

I too, have found that a basic nfpa 1002 class (pumps) is only the "basic foundation" of what a pump operator really needs. It's the foundation that has to be built upon. This is why I put together a training program to help out my brothers and sisters. You can get it at www.streetsmartpo.com

This website is in courtesy of Dutchess County Community College in New York. Should find the hydraulics spreadsheet a good start to pump operations.

Honestly, you're better off testing your own nozzles, hoses, and pumps. Not all are created the same and trust me on this one. I tested the pumpers and hoses and nozzles at both of my fire departments and found outrageous results that never came close to the hydraulics equations and answers. But just a food for thought for everyone else who rely too much on the textbooks and not actually test it out. You'll be amazed on how off are the textbooks.

Hello to all fellow Engineers.
I'm looking for some help on the great debate of Wet vs Dry pumps in the Chicago area.
