Because, Ron, it would need to be a fuse that is UL Listed for use with the 
Keg. (actuating device) But it would be fun to watch the test.

Why not just put a barrel of water on top of keg of black powder with a fuse 
going into the trailer?

Brad,
Don't forget to add a strainer

P = 40 PSI
K = 1.55
Q = 9.8 GPM

36 GPM / 9.8 = 3.67 holes per nozzle

call it 4 :)

Dude, you need serious help.   HAHA

Now how many average sprinkler designers could have figured that out?

But it has to equal the discharge of spray nozzles which are required to
provide a minimum of 36 gpm at 40 psi around the perimeter.

(.25/24)^2 * PI = .000314 ft^2
assume coefficient of discharge of .9
.000314 *.9 = .000283

'imply' 7 PSI
7 / .433 = 16.167 (h)
v = (2gh)^.5 = 32.266 ft/sec

32.266 ft/sec * .000283 ft^3 = .00913 ft^3/sec, * 7.48 * 60 = 4.1 GPM

Q = 4.1
P = 7.0
K = 1.55

Today's teaser.

An owner gives you this criteria for protecting a truck dock door opening.
A semi-trailer is parked at the opening up against the dock seal, the
trailer contains wooded pallets.

The rollup door and the trailer doors remain open at all times for in and
out access.

Their recommended method of protecting the opening is to use 1.5" pipe with
1/4" holes drilled every 6".  Provide this around the opening which is 12"
wide by 9' high.  This is approved by their international corporate safety
department.

This will be a deluge system for two dock doors.

How are you going to calculate this?
