3. 7.26 To determine the ullage of the liquid in a tank using an innage tape and bob assembly, what procedure should be followed? a. Read the immersion depth of the tape at the reference gauge point and subtract the oil cut reading on the bob b. Read the immersion depth of the tape at the reference gauge point and add the oil cut reading on the bob c. Subtract the oil cut on the bob from the tank reference gauge height indicated on the tank capacity table d. Subtract the oil cut on the bob from the measured tank reference gauge height
4. 7.13 What is a tank datum plate? a. The position on a tank where the gauge height is noted. b. The point marked on the gauge hatch of a tank to indicate the position from which the tank is to be gauged. c. The plate on the tank shell that lists the tank general data such as roof weight, height of tank, etc. d. A plate placed in the tank and directly under the reference gauge point to provide a fixed contact surface.
5. 7.40 If the density of a product within a tank is greater than the density of water, where would any free water in this tank be found? a. No free water would be found it as it would not settle out of this product but would remain in suspension b. On top of the product c. Below the product d. Answers a., b. and c. are all wrong
6. 7.44 How are free water measurements normally taken? a. By the innage method b. By the ullage method c. By the Heimlich method d. Answers a. and b. are correct

10. 7.55 What is the purpose of a floating roof correction in a shore tank calculation? a. To account for the compression of the liquid due to the roof weight b. To account for the volume of liquid displaced as a result of the weight of the roof c. To allow for the effect of the roof temperature on the temperature of the product d. To allow for the effect of the temperature on the thickness of the roof
11. 7.25 If a portable measurement unit (PMU) is used, which of the following procedures should be followed to measure free water on a vessel before discharge? a. Rely on the PMU alone for free water level measurement b. Use water-finding paste with a sounding rod/rule or dip tape c. Answers a. and b. are both correct d. Recommend to the terminal that the free water received and measured ashore be applied to the vessel figures
12. 7.51 If a tank s capacity table is an innage or dip table, what is the preferred method of gauging? a. Side Gauge b. Ullage c. Innage or dip d. Outage
13. 7.28 When gauging light products, it is permissible to use chalk or talcum powder to facilitate reading the cut on the tape. a. True b. False c. d.
14. 7.20 Which gauge measures the distance from the surface of the liquid to the tank reference gauge point? a. Innage or dip b. Ullage c. d.
