Question 1.
What is the main function of a reciprocating compressor?
Show hintHide hint
Think about what this machine does with air.
Question 2.
Name one key component of a reciprocating compressor.
Show hintHide hint
What do you need for movement?
3Question 3.
What is the main purpose of a reciprocating compressor?
- To compress air
- To heat air
- To cool air
Show hintHide hint
Think about the role of compressors in systems.
4Question 4.
True or False: Intercooling reduces the work input in multistage compression.
- True
- False
Show hintHide hint
Consider how cooling affects energy requirements.
Question 5.
If a reciprocating compressor operates at an inlet pressure of 2 bar and reaches a final delivery pressure of 8 bar in two stages, calculate the intermediate pressure needed for optimal work.
Show hintHide hint
Recall the pressure ratio formula we discussed for two-stage compressors.
Question 6.
Consider a scenario where the piston in a compressor is designed for a maximum pressure of 100 psi. If the inlet pressure is 20 psi, what should be the pressure ratio across the first stage to ensure minimal work?
Show hintHide hint
Think about how each stage should relate to maintain equal ratios for efficiency.
