1A rectangular public pool is 40 ft long by 20 ft wide with a uniform 5 ft water depth. Using 7.48 gal/ft³, what design flow is required for a 6-hour turnover?
A.83 gpm
B.67 gpm
C.100 gpm
D.125 gpm
Explanation: Volume = 40 × 20 × 5 × 7.48 = 29,920 gallons. Required flow = gallons ÷ (turnover hours × 60) = 29,920 ÷ 360 = 83.1 gpm. ANSI/APSP/ICC-1 2014 Table 8.1.1 caps Class A, B, and C pool turnover at 6 hours, so 83 gpm is the 6-hour design flow.
2A commercial pool holds 54,000 gallons and the circulation pump delivers 150 gpm with a clean filter. What is the turnover time?
A.4.0 hours
B.6.0 hours
C.8.0 hours
D.3.0 hours
Explanation: Turnover time in hours equals pool volume in gallons divided by flow in gpm times 60. Here 54,000 ÷ (150 × 60) = 54,000 ÷ 9,000 = 6.0 hours. That matches the ANSI/APSP/ICC-1 2014 Table 8.1.1 maximum of 6 hours for Class A, B, and C pools.
3Per ANSI/APSP/ICC-1 2014 Section 8.2, the water velocity in public-pool suction piping shall not exceed which value?
A.10 feet per second
B.8 feet per second
C.6 feet per second
D.3 feet per second
Explanation: APSP-1 2014 Section 8.2 limits suction piping to 6 fps and discharge piping to 10 fps, except copper discharge, which is limited to 8 fps. Keeping suction velocity at or below 6 fps reduces friction loss, cavitation risk, and suction-outlet loading.
4A public-pool return line is Type L copper. Per ANSI/APSP/ICC-1 2014 Section 8.2, what is the maximum permitted water velocity in that discharge piping?
A.12 feet per second
B.6 feet per second
C.10 feet per second
D.8 feet per second
Explanation: Section 8.2 allows 10 fps in discharge piping except copper, which is limited to 8 fps to reduce erosion-corrosion of the softer metal. Suction piping remains limited to 6 fps regardless of material.
5A public pool requires 120 gpm at the 6-hour turnover. Using a high-rate sand filter media rate of 15 gpm/ft² (NSF/ANSI 50 practice referenced by APSP-1 Section 9), what minimum filter area is required?
A.8.0 square feet
B.6.0 square feet
C.12.0 square feet
D.15.0 square feet
Explanation: Filter area = design flow ÷ media rate = 120 gpm ÷ 15 gpm/ft² = 8.0 ft². APSP-1 Section 9 requires filters to comply with NSF/ANSI 50 and not exceed the listed maximum flow of the media. Undersizing the area forces the filter above its NSF rating.
6A spa circulation system is designed for 80 gpm. Using a pressure diatomaceous-earth (DE) media rate of 2.0 gpm/ft², what minimum filter area is required?
A.16 square feet
B.40 square feet
C.80 square feet
D.20 square feet
Explanation: Area = 80 gpm ÷ 2.0 gpm/ft² = 40 ft². DE filters are listed under NSF/ANSI 50 at about 2 gpm/ft² for pressure units, so they need much more area than high-rate sand for the same flow.
7A pool filter system must handle 75 gpm. Using a cartridge media rate of 0.375 gpm/ft², what minimum cartridge area is required?
A.75 square feet
B.100 square feet
C.200 square feet
D.300 square feet
Explanation: Area = 75 ÷ 0.375 = 200 ft². Cartridge elements are rated far lower per square foot than sand, so a modest flow still needs a large listed area. NSF/ANSI 50 listings, which APSP-1 Section 9 requires filters to meet, commonly use 0.375 gpm/ft² for residential/commercial cartridge ratings.
8Per ANSI/APSP/ICC-1 2014 Section 12.3, when automatic surface skimmers are the sole overflow system, at least one skimmer is required for each how many square feet of water surface?
A.1,000 square feet
B.300 square feet
C.800 square feet
D.500 square feet
Explanation: Section 12.3 requires at least one surface skimmer per 500 sq ft, or fraction thereof, of water surface. Recessed stairs, swimouts, and spas are excluded from that area. Skimmers must also be located so they actually skim.
9Per ANSI/APSP/ICC-1 2014 Section 11.6, the number of return inlets shall be based on a minimum of one return inlet per how much pool surface area?
A.300 square feet
B.500 square feet
C.150 square feet
D.1,000 square feet
Explanation: Section 11.6 requires at least one return inlet per 300 sq ft of pool surface, or fraction thereof. Inlets must be sized or numerous enough to pass the full turnover flow and arranged for uniform circulation and sanitizer distribution.
10A new public pool suction outlet (other than a skimmer) must have a cover tested to which standard, as required by ANSI/APSP/ICC-1 2014 Section 11.2 and the Virginia Graeme Baker Pool and Spa Safety Act?
A.ANSI/NSF 14
B.ANSI/APSP-16
C.ASTM F1346
D.ANSI Z21.56
Explanation: APSP-1 Section 11.2 requires suction-outlet covers (other than skimmers) to be tested to ANSI/APSP-16 by an ILAC-accredited lab. VGBA likewise requires listed unblockable or dual-drain fittings. APSP/ICC-7 governs the piping arrangement that prevents entrapment.
