1. 2.36 How is Gross Observed Volume (GOV) defined?1) a. The volume read from the strapping table
2) b. The total volume of all petroleum liquids and sediment and water, excluding free water, at observed temperature and pressure
3) c. The volume read from the strapping table corrected for roof displacement
4) d. The volume used to calculate vessel ratios

2. 2.22 What is a floating roof tank?1) a. A tank in which the roof floats freely on the surface of the liquid contents at all levels.
2) b. A tank in which the roof floats freely on the surface of the liquid contents except at low levels when the weight of the roof is supported by its legs.
3) c. A tank in which the roof, supported by guide wires, can be adjusted to the required height for safe filling of the tank
4) d. Answers a., b. and c. are all wrong

3. 2.21 How is a running sample obtained?1) a. by lowering an unstoppered sampler from the top of the oil to the level of the outlet (Suction) and returning it to the top of the oil at a uniform rate so that the sampler is no more than 85% full when withdrawn from the oil.
2) b. by lowering a stoppered sampler to the level of the outlet, then opening the sampler and raising it at a uniform rate so that it is about 80% full when withdrawn from the oil.
3) c. by lowering a stoppered sampler to the mid point of the tank contents, then opening the sampler and raising and lowering it at a uniform rate until it is full
4) d. by lowering an unstoppered sampler to the mid point of the tank contents, then raising and lowering it at a uniform rate until it is full
|
4. 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.

5. 2.30 What is ullage?1) a. The depth of the empty space above the liquid in a tank
2) b. The height of the free water in a tank
3) c. The length of an ullage tape
4) d. The depth of the liquid in a tank
