Hydraulic behaviour in the FLAIM FTS T2 and T3 system is standardised to ensure consistency of training outcomes. At approximately 150 GPM, flow characteristics align most closely with a 1¾" (45 mm) attack line, with an implicit assumption of a typical deployment length of around 30 m (100 ft equivalent).

Friction loss and pump discharge pressure (PDP) behaviour are embedded within the simulation model and are not exposed as user-adjustable hydraulic variables. The 1¾" behaviour should therefore be interpreted as an equivalent representation for training purposes — the goal is to allow firefighters to practise drills and skills (door procedure, gas cooling, search and rescue) rather than replicate hydraulically precise fire behaviour.
