Practice question
Why does water accumulation in the air tanks reduce the total volume of air available for braking, and what is the thermodynamic result on system pressure recovery?
- Water molecules destroy the compressor's air filter
- Water is incompressible and takes up tank volume, causing the compressor to cycle more frequently and causing pressure to drop faster during applications
- Water increases the density of the air, raising cut-out pressure to dangerous levels
- Water causes the desiccant inside the air dryer to expand and block all airflow
Answer: B — Water is incompressible and takes up tank volume, causing the compressor to cycle more frequently and causing pressure to drop faster during applications
