If a 1 1/4-inch solid stream nozzle is flowing at 50 psi, then you know the gpm is approximately: a. 524 b. 636 c. 475 d. 328 - correct answer d. 328 Determine the TPL for a hose assembly in which two 700-foot sections of 2 1/2-inch hose and one 700-foot section of 3-inch hose with 2 1/2 inch couplings are siamesed together to supply 300 feet of 3-inch hose with 2 1/2 inch couplings. Flow is 200 gpm. a. 18.46 psi b. 22.53 psi c. 30.71 psi d. 14.08 psi - correct answer d. 14.08 psi Determine the TPL for a hose assembly in which 400 feet of 5-inch hose is wyed into one 200-foot section of 2 1/2-inch hose and one 300-foot section of 2 1/2-inch hose. Each attack hose is flowing at 200 gpm. a. 19 psi b. 54 psi c. 39 psi d. 29 psi - correct answer c. 39 psi One of the assumptions of a maximum distance relay method is that: a. there is 20 psi of residual pressure at each relay pumper b. there is 40 psi of residual pressure ate each relay pumper c. to pump 500 gpm, a pumper's rated capacity must be 1000 gpm

Identify the true statement about a multi-stage fire pump a. The PARALLEL/VOLUME position gives you maximum pressure over an extended period b. The PARALLEL/VOLUME position gives you maximum pressure for a short period c. The SERIES/PRESSURE position gives you maximum flow over an extended period d. The SERIES/PRESSURE position gives you maximum pressure for a short period - correct answer c. The SERIES/PRESSURE position gives you maximum pressure for a short period When controlling pump valves, push-pull handles: a. are superior to quarter-turn handles because they can operate butterfly valves b. are inferior to quarter-turn handles because they cannot be locked into place. c. are best when applied only to butterfly and gate valves d. can accurately control line pressure and be locked into place. - correct answer d. can accurately control line pressure and be locked into place. One characteristic of discharge pressure relief valves is that they: a. can only maintain set pressure under 250 psi b. are slow to close after being opened c. are slow to return to their open position after being closed d. are impossible to operate from a remote switch. - correct answer b. are slow to close after being opened The pump whose rotor is mounted off-center is the: a. centrifugal pump b. rotary vane positive displacement pump c. rotary gear positive displacement pump

d. centripetal pump - correct answer b. rotary vane positive displacement pump When using a standard fog nozzle with Class A foams, little or no performance improvement has been shown in concentrations over: a. 0.5% b. 1.5% c. 1.0% d. 2.0% - correct answer a. 0.5 % The purpose of the priming test is to: a. check the overall condition of the pump b. evaluate how quickly the priming device can create a vacuum to bring water through a pump to the discharge hose c. check that the given discharge information is accurate when the pump is in operation d. check for leaks in the system vacuum pressure, priming device, and pump - correct answer b. evaluate how quickly the priming device can create a vacuum to bring water through a pump to the discharge hose The purpose of the gauge and flowmeter test is to: a. check the overall condition of the engine b. check that the given discharge information is accurate when the pump is in operation c. ensure that the fire apparatus is running at the same speed it was rated for when it was new d. measure whether pressure control devices can maintain certain discharge pressures under varying conditions - correct answer b. check that the given discharge information is accurate when the pump is in operation

c. 3% d. 6% - correct answer c. 3% Testing a flowmeter consists of: a. closing the discharge valve without changing the throttle setting b. disconnecting all preconnected hoselines and screwing all caps onto their discharges c. connecting a hoseline equipped with a solid stream nozzle to each discharge being tested d. closing all of the flowing valves one at a time - correct answer c. connecting a hoseline equipped with a solid stream nozzle to each discharge being tested
