Manitoba Airbrake Practice Exam

The first air tank that air enters is called what?

1. Dry tank

2. Wet tank

3. Main tank

4. Reserve tank

The correct answer is: Wet tank

The first air tank that air enters is called the wet tank. This is because it is the first tank to receive air from the compressor, and therefore it is "wet" with air. The other options, such as the dry tank, main tank, and reserve tank, are all incorrect because they do not accurately describe the purpose or function of the first tank in the air system. A dry tank refers to a tank that does not contain any fluids, but the first air tank in an air system is not necessarily dry. The main tank and reserve tank may refer to tanks that are used for storage or reserve purposes, but they do not specifically indicate the initial tank that air enters. Therefore, these options are not as accurate as the correct answer, which is the wet tank.
