Which of the following is NOT a factor affecting force exerted by liquids in an open tank?
- Size of tank
- Specific gravity
- Liquid height
- Temperature
Which of the following statements is most accurate concerning the placement of a measuring device?
- The placement of the measuring device has no bearing on the recorded pressure
- The height of liquid above the measuring device will determine the amount of pressure measured
- For the most accurate measurement, the measuring device must always be placed at the bottom of the tank
- To ensure proper measurement, the measuring device should be placed at the highest point
What is specific gravity?
- The comparison of water temperature to mercury
- The ability of a liquid to resist gravity
- A comparison of the density of a liquid compared to that of water
- The general weight, in pounds, of a liquid
