Which factor is specific to pneumatic systems when considering efficiency?

• A. Compressor efficiency
• B. Fluid viscosity
• C. Leaks
• D. Pressure losses in hydraulics

Answer: (A)

In pneumatic systems, the stored energy is in the compressed air, so how efficiently that energy is created matters most. The compressor efficiency measures how effectively electrical power is converted into usable compressed air. If the compressor wastes energy as heat or suffers mechanical losses, the entire system becomes less efficient, even if downstream components are well designed and leaks are minimized. Other factors aren’t unique to pneumatics in the same way. Fluid viscosity concerns the working fluid’s resistance and is more impactful in liquid systems; leaks and pressure losses in hydraulics pertain to non-pneumatic systems or downstream losses, not the primary energy conversion step. So the compressor’s efficiency is the factor that most directly and specifically controls efficiency in pneumatic setups.
