FAE Questions and Answers Already Passed The speedometer on an apparatus is primarily used to show speed but may also indicate the pump is turning To calculate friction loss in 2 1/2" fire hose when the flow is near 100 gpm, which of the following formulas should be used? FL=cq(2)L The pressure remaining once water has begun flowing is known as _____ pressure. residual When the flow through a hose line increases from 100 gpm to 400 gpm, the friction loss increases _____ times. 16 the recommended pressure for a standard fog nozzle is 100 PSI The foam application technique that directs the foam stream on the ground near the front edge of a burning liquid pool or spill is the: roll on method Master stream nozzles are: Either solid of fog streams _________ consist of small return (bypass) water line connected from the discharge side of the pump back to the intake side of the pump around the pump proportioners which type of nozzle is very effective when fighting a fire in a basement or cellar distributors nozzle if the inlet pressure to the eductor is too high foam may not be inducted when lowering a barrel strainer into the water, it should have _____ inches of water in all directions 24 an increase in vacuum while drafting may indicate a clogged strainer hose that is laid from the fire to the hydrant is considered a reverse lay a straight stream is considered a pattern of an adjustable fog nozzle pump discharge pressure is equal to Nozzle pressure + friction loss as flow increases, pressure will ___________ provided pump seal remains constant increase the primary function of the fire department pumper is to provide water at an adequate pressure for fire streams Once the power take off has been properly activated and the pump is engaged, the vehicle speedometer should show a speed of: slightly above 0 mph the maximum height water can be drafted is approximately __________ feet, as opposed to the theoretical lift of 33.8 feet 25 feet You should switch from pressure to volume mode when more than half of the rated capacity of the pump will be required when using foam to extinguish a fire, the separating method creates a barrier between the fuel and the fire
