Ok guys I'm not familiar enough with power source requirements so looking for
guidance.
I have a client trying to some how get out of buying the Fire Pump with a
transfer switch.
This is located in Cambodia so it's not looking good. It's in the capital but

Well Roland consider thisthe building code requires a rated door between
living space and a garage, but no requirement for a closer.

That is my understanding (despite the fact that a door is not required to the
adjacent room). Never said it ad to be logical.

E.G like this:

I'm looking for a quick sanity check. We are an A/E firm designing new college
dormitories. These dorms typically contain four bedroom suites with two
bathrooms in each suite. The 1987 edition of 2013 is applicable, and the
bathrooms are less than 55 square feet. In order to omit sprinklers
Hmmm.. I wonder if there is any way we can figure out how fast water would have
to be going to exert a velocity pressure of 5 psi? Could we slap ourselves on
the forehead and say Hey- the old Law of Falling Bodies works here. ?

That has always been understood but was stated in the 2013 ed (section 1.1.3)
to put a final nail in the coffin of that issue.

Can anyone out there explain why TIA 13-2 was issued? Without reading
it line-by-line, whatever revisions it contains seem pretty subtle.

Tim, So based on 47 psi at one test valve and just a flow on the rest, what was
the pressure on the suction flange of the pump? Can't you just plot 1500 gpm on
flow test curve and subtract the friction and elevation losses between the
supply and pump?
Brian, Pitot the discharge for each outlet
Are you trying to determine a pressure so you can assign a k-factor to the test
header outlets?
Why not just put a fixed flow from each test connection outlet and then see
what the pressure is and how that compares to the pump rating?
Do you have a flow test showing what's going into the pump?
Ron,
In my case the EOR was worried about negative pressures on the suction
flange before the sprinkler contractor ordered the pump.

Okay, what am I missing? There are gauges on the suction and discharge sides of
the pump, right?

Brian,
I just performed this on a warehouse project with a diesel fire pump taking
suction from a municipal water supply. The EOR wanted to know the pressures
on the Suction Flange of the pump.
I started off with 375 GPM on each test header valve and assigned a pressure
of 47 PSI to one of the val
Why not just read the gauges on the pump?

I'm running a theoretical calc on a pump test header to try and determine if

Hey all,
When you are calculating a manual standpipe, can you utilize the pump on the
truck along with city flow in your calculations? Typically I have always
just utilized the truck instead of adding the truck to city flow.
Thanks in advance!
