Welcome to our Online Pneumatics Quiz.  The quiz below should be administered to all maintenance personnel responsible for pneumatic equipment. A score of less than 70% is a strong indication that  GPM's Basic Pneumatic Maintenance and Troubleshooting workshop could reap significant savings in unnecessary down time and parts cost.

1) Pascal’s Law states that pressure in a confined body of fluid acts _________in all directions.
2) If a cylinder has 30 square inches of area on its full piston side, how much force can be developed to extend the cylinder if pressurized to 100 PSI?
3) If the temperature of a gas increases and the pressure remains constant, what happens to the volume of the gas?
4) The temperature at which water vapor condenses out of the air and turns into liquid water is known as the__________________.
5) How many cubic feet of outside air is required to produce 1 cubic foot of air compressed to 100 PSI?
6) The absolute pressure of a confined body of gas varies _________ as its volume changes, provided the temperature remains constant.
7) When piping a distribution air system, how much should the pipe be sloped downward to allow condensate to flow to a low point to be removed by a drain valve?
8) Which of the following will a filter NOT remove from the air line?
9) The distance between a secondary filter and the component it protects should be no more than:
10) True or False.  An air regulator can be mounted in any position.
11) The symbol shown below represents what type of pneumatic component?

nonrelieving regulator

  1. A good rule of thumb to use for operating an actuator at normal speed is to set the air regulator _________ higher than the pressure required to move the load.

13) What kind of pneumatic component does the symbol shown below represent?

air lubricator

  1. True or False. It is better to over lubricate than under lubricate.
