1. 2.27 What is the Reference Gauge Height of a tank?1) a. The distance from the tank top to the tank bottom
2) b. The distance from the ullage hatch to the datum plate
3) c. The distance from reference gauge point to the tank bottom or datum plate
4) d. The distance from tank bottom to the ullage hatch
| 2. 2.15 What is Total Observed Volume (TOV)?1) a. The total measured volume of all petroleum liquids, sediment and water, and free water at observed temperature
2) b. The total measured volume of all petroleum liquids, sediment and water but excluding free water, at observed temperature
3) c. The total volume of all petroleum liquids and sediment and water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
4) d. The total measured volume of all petroleum liquids excluding water and sediment, at observed temperature
| 3. 2.09 What is a datum plate?1) a. A level metal plate located directly under the reference gauge point to provide a fixed contact surface from which liquid depth measurement can be made.
2) b. A metal plate located next to the gauging point on a tank indicating the reference gauge height.
3) c. A metal plate located close to the gauging point on a tank listing all the relevant tank data
4) d. A level metal plate located at the top of a gauge hatch on a tank from which the gauge height is measured.
| 4. 2.18 What is Net Standard Volume (NSV)?1) a. The total volume of all petroleum liquids, excluding sediment and water and free water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
2) b. The total volume of all petroleum liquids, excluding sediment and water, but including free water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
3) c. The total volume of all petroleum liquids and free water, excluding sediment and water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
4) d. The total volume of all petroleum liquids and sediment and water and free water, corrected to a standard temperature by the appropriate volume correction factor for the observed temperature and density
| 5. 2.20 How is an all levels sample obtained?1) a. By submerging an unstoppered sampler to a point near the tank draw-off outlet (suction) level and then raising it, all at a uniform rate, so that it is no more than 85% full on emerging from the liquid.
2) b. By blending upper, middle and lower samples from the same tank.
3) c. By submerging a stoppered sampler to a point as near as possible to the draw-off outlet (suction) level, then opening the sampler and raising it at a rate such that it is no more than 80% full as it emerges from the liquid.
4) d. By submerging a stoppered sampler to the mid point of the product in a tank, then opening the sampler and raising and lowering it at a uniform rate until the sampler is full.
