Minuteman load – A special load that allows the firefighters to pull a large section of the hose onto their shoulders and have it drop off (called "paying out") in an organized fashion as they advance towards the fire. [8] "S" load, more commonly known as the "triple-layer" load – The hose is folded three times before being loaded.
The hydraulic calculation procedure is defined in the applicable reference model codes such as that published by the US-based National Fire Protection Association (NFPA), [2] or the EN 12845 standard, Fixed firefighting system – Automatic sprinkler systems – Design, installation and maintenance.

In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
Triple deck theory is a theory that describes a three-layered boundary-layer structure when sufficiently large disturbances are present in the boundary layer. This theory is able to successfully explain the phenomenon of boundary layer separation, but it has found applications in many other flow setups as well, [1] including the scaling of the lower-branch instability of the Blasius flow, [2 ...
Like its predecessor, the M3 traverses roads on its four wheels, deploying two large aluminium pontoons for buoyancy on water. The M3 is 1.4 metres (4.6 ft) longer and 3,300 kg (7,300 lb) heavier than the M2, with the M3 having a turn diameter of 24 metres (79 ft).
The size can be from 2” to 6”. These 3 pipes are connected by swivel joints. Swivel joints are required to provide the flexibility needed. The loading arm unfolds to get the required working envelope to load or unload the tanker, and the reverse is to retract or get a minimal space for parking or storage. Both types of loading arms may be ...
The first of the cooling load factors used in this method is the CLTD, or the Cooling Load Temperature Difference. This factor is used to represent the temperature difference between indoor and outdoor air with the inclusion of the heating effects of solar radiation. [1] [5] The second factor is the CLF, or the cooling load factor.
System of Systems Engineering (SoSE) methodology is heavily used in U.S. Department of Defense applications, but is increasingly being applied to non-defense related problems such as architectural design of problems in air and auto transportation, healthcare, global communication networks, search and rescue, space exploration, industry 4.0 [1] and many other System of Systems application domains.
