1Turnover time is best defined as the period required to:
A.Pass a volume of water equal to the pool capacity through the circulation and filtration system
B.Raise free chlorine from zero to the residual used for swimming
C.Backwash a high-rate sand filter until the sight glass runs clear
D.Heat the pool 10°F with the installed heater
Explanation: Turnover is the time needed for a volume of water equal to the pool capacity to pass through the pump, filter, and returns. USPSHTC 2018 sizes private-pool equipment from this period so sanitizer and filtered water actually reach the entire vessel.
2A rectangular residential pool is 16 ft wide by 32 ft long with a 5 ft average depth. Using 7.48 gal/cu ft, what is the water volume?
A.14,400 gallons
B.19,150 gallons
C.21,500 gallons
D.25,600 gallons
Explanation: Volume (gal) = length × width × average depth × 7.48. 16 × 32 × 5 × 7.48 = 19,148.8 gallons, about 19,150 gallons. This volume is the starting number for USPSHTC turnover and flow-rate sizing.
3A 20,000-gallon private residential pool must meet the USPSHTC 2018 8-hour maximum turnover. What minimum circulation flow is required?
A.28 gpm
B.42 gpm
C.56 gpm
D.83 gpm
Explanation: Required flow (gpm) = volume ÷ (turnover hours × 60). 20,000 ÷ (8 × 60) = 20,000 ÷ 480 = 41.7 gpm, so the system must deliver at least about 42 gpm with clean filter media.
4A 24,000-gallon residential pool circulates at 50 gpm. What is the turnover time?
A.6 hours
B.7 hours
C.8 hours
D.10 hours
Explanation: Turnover hours = volume ÷ (gpm × 60). 24,000 ÷ (50 × 60) = 24,000 ÷ 3,000 = 8.0 hours. That equals the USPSHTC 2018 private-pool maximum.
5Per USPSHTC 2018, what is the maximum turnover time for a private (residential) swimming pool?
A.4 hours
B.6 hours
C.8 hours
D.12 hours
Explanation: USPSHTC 2018 requires matched circulation components to turn a private pool over in not more than 8 hours. Public pools are held to 6 hours; do not apply the public figure to an A-10A residential pool.
6A-10A work includes residential spas. Spa circulation equipment is sized on which maximum turnover time, the same figure NAC 444.484 requires of public spas in Nevada?
A.15 minutes
B.30 minutes
C.1 hour
D.8 hours
Explanation: Spa circulation and filtration equipment is sized on a 30-minute turnover. NAC 444.484 states that public spa equipment must recirculate the entire spa water capacity at least once every 30 minutes, and the same 30-minute figure is standard spa practice for residential spas because the small volume and high bather load per gallon demand rapid filtration. Divide gallons by 30 to get the design gpm.
7A residential circulation system must deliver 60 gpm. If a high-rate sand filter is rated at 20 gpm per square foot of media, what minimum filter area is required?
A.2 sq ft
B.3 sq ft
C.4 sq ft
D.6 sq ft
Explanation: Filter area = design flow ÷ allowable media rate. 60 gpm ÷ 20 gpm/sq ft = 3 sq ft. High-rate sand is commonly listed at 15–20 gpm/sq ft under NSF/ANSI 50; using the 20 gpm/sq ft listing gives this minimum area.
8A cartridge filter is listed at 0.375 gpm per square foot. What minimum media area is required for a 37.5 gpm design flow?
A.50 sq ft
B.75 sq ft
C.100 sq ft
D.150 sq ft
Explanation: Area = 37.5 gpm ÷ 0.375 gpm/sq ft = 100 sq ft. NSF/ANSI 50 cartridge listings commonly use 0.375 gpm/sq ft; undersizing the media raises differential pressure and shortens cartridge life.
9The primary purpose of a surface skimmer is to:
A.Draw dirty surface water and floating debris into the circulation system
B.Provide the only legal suction outlet under the Virginia Graeme Baker Act
C.Increase heater recovery by pulling from the deepest water
D.Relieve hydrostatic pressure under the pool floor
Explanation: Most oils, sunscreen, and floating debris collect at the surface. USPSHTC requires surface skimmers or a perimeter overflow so that surface water is continuously removed. A skimmer is not a hydrostatic relief device and is not, by itself, a VGB suction-outlet cover.
10A rectangular residential pool is 18 ft by 36 ft. If one skimmer is required for each 500 sq ft of surface (or fraction thereof), how many skimmers are required?
A.1
B.2
C.3
D.4
Explanation: Surface area = 18 × 36 = 648 sq ft. 648 ÷ 500 = 1.3, so two skimmers are required. The fraction-thereof rule always rounds up.
