What is the permissible operating range for a listed fire pump rated for 1000 gpm @ 80 psi? Provide examples from two specific manufacturers and attach product information. What maximum pump rating, in gpm, should be used on a water supply that can deliver a static pressure of 75 psi and a residual pressure of 50 psi when 1600 gpm is flowing?The city water in Cambridge, MA has been determined to have the following flow data based on a recent hydrant flow test: 60 psi static 50 psi residual @ 1,500 gpm Plot the city water supply, pump curve and combined curve of a 1000 gpm, 60 psi horizontal split-case fire pump. Assume the pump curve corresponds to the limits set by NFPA 20. If a sprinkler system demand is 1200 gpm at 68 psi, what minimum size horizontal split-case pump taking such from the following water supply system (static: 49 psi, flow: 2000 gpm @ 25 psi) will provide the necessary water supply? Identify a specific pump and provide manufacturer’s data.A diesel-driven centrifugal fire pump is rated at 1200 gpm at 100 psi with a churn pressure of 145 psig. Static city pressure varies between 60 and 70 psig. Determine if a relife valve is required, and the pressure settings for the following: -Jockey pump stop - Jockey pump start - Fire pump stop - Fire pump start - Fire pump maximum churn A high rise building has a pump located at ground level that produces 160 psig at the pump outlet at churn and 150 psig at the design sprinkler system flow. The standpipe is oversized so that friction losses are negligible in the riser. The pump must be able to supply a minimum of 47 psig to the sprinkler system located on the 18th floor (sprinklers are located at the ceiling, 185-ft above ground level). The pump is set to operate when a pressure switch mounted at the pump outlet senses that the pressure has dropped to below 90 psig. Once operating, can the pump adequately supply the sprinkler system on the 18th floor? Will the pump start automatically? A pump rated at 1760 rpm delivers 1250 gpm while developing a net pressure of 50 psi and 38.4 horsepower during the pump test. The pump speed during the test was measured at 1900 rpm. What is the corresponding flow and pressure if the pump was actually operating at 1950 rpm? A fire pump rated for 1500 gpm and 100 psi at 1750 rpm has a shut off pressure of 120 psi. An engine governor limits engine speed to 110% of rated speed. A static pressure of 45 psi is available from the fire service main. Is a pressure relief valve needed? Explain. An underground fire service main in a methanol plant consists of glass reinforced plastic material. The piping is rated for 200 psi. The pump’s churn pressure is rated at 280 psi. Numerous leaks have been experienced. Discuss the problem and potential solutions. An electric motor driven horizontal split case fire pump and a jockey pump are proposed for a high-rise building. The building has 3 stairwells. One combined sprinkler/standpipe riser is used, while two separate standpipe systems are used in the other two stairwells. The sprinkler system requires lower pressure than the standpipe system in the distribution piping so a pressure-reducing device is being considered. Draw a diagram representing the pumping and piping arrangement including all required appurtenances for the installation. Use the following symbols and abbreviations: Fire pump Jockey pump Test header Fire department connection (FDC) Pressure gauge Check valve Gate valvePressure Reducing Device
