When most of
us were in school taking an “Algebra Class”. We all
said those magic words, “Why do I need to learn math.
I’m not gonna use it in the real world.” Well I
do.
I work
for a Fire Department here in the valley. I hold the rank of
Engineer or Apparatus Operator (AO). I get to drive the fire
engines and trucks all around. When I am working on the engine, I
have to supply water to the firefighters from the engine using
hydraulic calculations.
These
calculations are figured out by using algebra. Now I don’t
have to sit and figure out every problem I come across because we
have standard hose operations with a set pressure. We have rule of
thumb flow rates and calculations. Most importantly, we have our
“Pumper Data Sheets” that have most of this information
printed out on them.
Your
assignment, if you choose to do it, is to figure out some hydraulic
calculations to pass this mini promotional exam. I have given you a
“Pumper Data Sheet” with four (4) problems. The data
sheet has most everything you need to figure out how solve the
problems. You might need to search the internet to find some
information because it is basic information taught in the fire
academy.
Once you
have the answers for each problem you will now need to add or
subtract your answers from the following problems to find ground
zero.
N38
mm.mmm W121 mm.mmm
North mm =
163 - answer from problem 1
North mmm =
488 + answer from problem 2
West mm =
145 - answer from problem 3
West mmm =
668 + answer from problem 4
