IFSTA Chapter 7 Theoretical Pressure Calculations Flashcards
1
Q
Primary function of the engine driver/operator on the fireground
A
Provide water to attack crews in sufficient volume and pressure to achieve control and extinguishment of fires
2
Q
List all 4 elements of friction loss
A
Hose size, couplings and kinks, but primarily the volume of water flowing per minute
3
Q
Two hose lines of equal length are Siamesed to supply a fire stream, friction loss is lowered by how much
A
25% less than that of a single hose at the same nozzle pressure
4
Q
Determine Net Pump Discharge Presure
A
NDPD= PDP - Intake Pressure
