Heat Gradient Calculation

Improving the lines of attack

.
out compartment located in the bed of attack, this makes hoses are previously connected.


L idea of \u200b\u200bputting a line of "fast attack" is to arrive as quickly as possible with sufficient capacity to crush 80% of our fires with a length that allows to reach the back of a house, that is, must have 3 or 4 hoses of 15 meters (45 to 60 m in length) with hoses of 52 mm in diameter to ensure the flow rate of approximately 1,000-python LPM to 7 bar or less depending the type of python.
This is an undisputed copy lines pre-connected to American bombs, but a lot of our bombs at national level, do not bring out in the same compartment hose, ie not are pre-connected.

This is a problem, because the fast break is not connected nothing, forcing tail being switched to a pump outlet . The attack must be the least cumbersome possible and should facilitate the deployment of hoses by one man.

.
addition our copies are made in compartments very young, which leave no choice to make a bed with many folds perpendicular very short impossible to load several meters of hose over the shoulder (this forces the pitonero practically carry only the end of the spigot). A bed longer allows pitonero load on his shoulder, moving through corridors and stairways to the second floor of the structure stricken.

Error and Solution.

the queue is usually hidden in the bottom of the compartment with many folds perpendicular with respect to the direction pump.

The solution (easy and economic ) is to leave the queue always see an extra section to reach the exit of the pump.

fast attack The idea is to make it easy , comfortable and of course quick to deploy only a firefighter, without the help of others thought of those days when the number of the crew is very low.

Once connected 'attack' located in parallel to the pump, pitonero only have to worry about and move to rectify to the fire.
