ANS:C - 3000

The maximum delivery pressure of a reciprocating compressor is typically around 3000 kg/cm². Therefore, the correct answer is: 3000 The maximum delivery pressure of a reciprocating compressor refers to the highest pressure that the compressor can achieve when it compresses gases or air. This pressure is crucial because it determines the compressor's capability to generate high-pressure outputs, which is often necessary in various industrial applications. In the context of the question, the options provided are:

• 1000 kg/cm²
• 2000 kg/cm²
• 3000 kg/cm²
• 4000 kg/cm²

Among these options, 3000 kg/cm² is considered a typical maximum delivery pressure for many reciprocating compressors. This level of pressure is sufficient for a wide range of industrial uses where compressed air or gases are needed at high pressures, such as in manufacturing processes, pneumatic tools, and various chemical and petrochemical applications. Therefore, when it's stated that "the correct answer is 3000 kg/cm²," it means that this value represents a common and typical maximum delivery pressure for reciprocating compressors in industrial settings.
