Question 1.
List three key components of a reciprocating compressor.
Show hintHide hint
Think about the main parts that would allow compression to occur.
Question 2.
What is the basic equation representing the polytropic process?
Show hintHide hint
Remember the format where pressure is multiplied by volume.
3Question 3.
What is the primary function of a reciprocating compressor?
- To cool down gas
- To compress air or gas
- To filter air
Show hintHide hint
Think about what compressors do in systems.
4Question 4.
True or False: Multi-stage compressors always have equal pressure ratios across all stages.
- True
- False
Show hintHide hint
Recall the concept discussed about pressure ratios.
Question 5.
A reciprocating compressor has an inlet pressure of 1 bar and a final pressure of 8 bar. Calculate the optimal stage pressure ratio if it operates in 3 stages.
Show hintHide hint
Break it down: first find the ratio of pressures.
Question 6.
If a reciprocating compressor operates at k = 1.4 and uses perfect intercooling for a state where P_1 is 5 bar and P_2 is 15 bar, calculate W_min.
