MWS CDC- 190 questions- with complete solutions

Identify five reqiuremennts for an MWS app that can be found in NFPA1901 correct answer: visual/ operational checks and preventative maintenance Preservice pump certification tests are conducted by correct answer: An independent testing agency If the engine speed check proves the MWS app is running at a different speed than that which it was originally rated you need to. correct answer: Stop the testing until the problem is corrected When conducting the priming device test and using a pump of less than 1500 gpm the priming device should be able to create the necessary vacuum in ___ sec to lift 10ft through 20ft of hard section hose correct answer: 30 sec Pumping test in the correct order correct answer: 1 gradually speed up the pump until the net pump discharge pressure is 150 psi 2 use a pitot tube or flowmeter to check the flow of water at the nozzle 3 record six diffrent readings at 5 min intervals for a total of 2o min Set the net pump discharge pressure to 200psi Set the net pump discharge pressure to 250psi The three parts of the pressure control test requires you to coles the flowing valves one at a time correct answer: No less than 3 sec no more than 10 sec The guage and flow test compares flowmeter readings with actual pitot tube readings. The two readings should differ by no more than: correct answer: 10% The tank to pump rate test mesures whether the pimping between an apparatus water tank anf the fire pump meets the minimum flow standards of correct answer: NFPA 1901 Match the equipment needed for conducting fire pump service test with its correct function. Checks the pump intake pressure Checks engine speed Needed to match the volumes pumped for the different test Secures test nozzles Measures the velocity pressure of a stream of water Reads the flow of water directly in gpm correct answer: Compound guages Tachometer Solid stream nozzle Rope or test nd Pitot tube Identify the two most important reasons for maintaining good MWS app records correct answer: Keeps everyone on the team informed about equipment conditions Helps determine whether equipment should be repaire
