🔍 Key Concepts

• Compression ratio in a reciprocating air compressor (ratio of absolute discharge pressure to absolute suction pressure) • How discharge pressure changes when the compression ratio is increased above design • What happens to displacement capacity/volume flow when the compressor is forced to work against a higher pressure than it was designed for

💭 Think About

• If the compressor is compressing to a higher final pressure than designed, what does that do to the temperature and density of the air at discharge? • When discharge pressure rises above design, does it become easier or harder for each stroke to push its full designed volume of air out of the cylinder? Why? • Think about valve operation: at excessively high discharge pressure, how are the suction and discharge valves affected during each stroke?

✅ Before You Answer

• Be clear that compression ratio is based on absolute pressures (psia), not gauge pressure (psig) • Decide whether an increased compression ratio would tend to increase or decrease the actual mass/volume of air delivered per unit time • Check that the option you pick shows a consistent pair: a higher-than-designed compression ratio should not give you a discharge pressure trend that contradicts basic physics (higher ratio vs lower/higher discharge pressure).
