FAE (Fire Apparatus Engineer) Illinois Test 2 024-2025 With comple te solutions In a Relay operation how much Pressure should relaying pumper make sure the receiving pumper is getting? - Maintain 20 psi for receiving pumper A relay directly between pumps - Closed Relay Evaluation consisting of written test accuracy of 70%, from m emory, without assistance. Cognitive - Cognitive Engine/Auxiliary coolers permits water from pump to cool radiator water by means of a heat exchanger - Cooling Devices The difference between static and residual pressures as found on the compound gauge. - Drop Two pumpers connected independently to the same fire hydrant. - Dual Pumping Used primarily on portable pumps where the velocity of exhaust gases passing through a venturi creates a vacuum. Require High engine RPM and is not very efficient. - Exhaust Primers Usually consists of several feet of copper tubing through which a liquid (oil or water) passes and excessive heat is absorbed. Heat exchangers - Heat exchangers The Pressure found on a water distribution system during normal consumption demands. - Normal Operating Pressure Oil from the engine crankcase is kept at an even temp erature by cool water within the bottom of the radiator by means of an internal heat exchanger - Oil coolers Permits water from the pump to directly enter the radiator. - Radiator Fill Valves The point at which the decisions should be made to either add a line to help deliver the desired GPM or to use a larger sized line. Any time the GPM desired produces a Friction Loss of approximately 36 psi/100 feet of hose, the "Red Line" has been reached. - Red Line Residual Pressure - That part of the total pressu re that is not used to overcome friction or gravity while forcing water through fire hose, pipe, fittings, and adapters. To perform the objective without injury to self or to others, or damage to fire department vehicles and equipment. - Safely Two Pumpe rs connect in series to a fire hydrant. One pumper connected to hydrant, with a second pumper obtaining its water supply from excess water obtained from the intake of the first. - Tandem Pumping Makes use of the vacuum already present in the intake manifo ld of a gasoline engine. - Vacuum Primers caused by tubercular corrosion or rust, caused by chemical constituents of the water, caused by growth of biological or living organisms. - IncrustationThe benefits of buying summaries with Stuvia:
