    Question Hydraulic Calculators

    Hi,
    You guys are probably going to ding me for this but yes......I was wondering if anyone knew of a calculator that does hydraulics. I don't want to abuse a PDA in the field and I'm tired of pump charts missing or getting destroyed. Was hoping that there was a durable hydraulic calculator somewhere on the market. We rotate engines often which have different set ups on them with no uniformity, so one day your preconnects are 1 3/4 200 ft. the next day they are 2.5 and 300 ft. We never get the chance to really know our engines like the back of our hands and am getting tired of calcing GPM=29.7 X d2 X square root of NP...............ya know.
    Thanks for any feet back..

    Akron has the Fire Calc, I got mine from www.fire-end.com/FireCalc.html easy to use, just plug in the numbers.

    You could, of course, standardize the apparatus and the hosebeds so the hydraulics would be easier... The Akron FireCalc is the best for quick work on the firegroiund. Their slide rule isn't too bad either.

    I was going to suggest the Akron FireCalc but everyone beat me to it. Great little gadget, easy to use for friction loss, engine pressures, needed fire flow...also adds, subtracts, multiplies,and divides

    My suggestion would be to calculate the needed engine pressures for the various setups you normally encounter, then print them on a laminated card and give one to every driver/operator. Better than punching numbers at the fire scene. The FireCalc is easy and quick, but a glance at a card is quicker.

My dream and I hope you don't find this too crazy is that I would like the people of this community to feel that if, God forbid, there were a fire, calling the fire department would actually be a wise thing to do. You can't have people, if their houses are burning down, saying, 'Whatever you do, don't call the fire department!' That would be bad."

    Default Flow meters

    The Fireclac is great, but one word from experience here - get some flow meters on your hoses and see what they actually flow at the recommended or formula calculated pressures. You would really be suprised what the differance in actual flow rates of the various brands of hose of the same diameter there is!! And standarizing the preconnected lengths is a great sugestion. Makes things a LOT easier!!








    Send in another nozzle, this one's melting!

    Well, I'm now an official owner of one of those Firecalcs. I figured on being in this position awhile so what the heck. I'll keep you posted on how things work out.
    NOTE: All hands.com shipping was a lot better than the other place. I paid $8 ground at allhands.com and they quoted me $15 ground at the other company.
    Stay safe,
    Scott
