Mechanical Engineering : Compressors QUESTIONS AND ANSWERS :: part3 : 16 to 20
Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :
16.The criterion of the thermodynamic efficiency for rotary compressor is |
| isentropic compression |
| isothermal compression |
| polytropic compression |
| any one of the above |
| none of the above. |
17.As the value of index '�' is decreased, the volumetric efficiency will |
| increase |
| decrease |
| remain unaffected |
| may increase/decrease depending on compressor clearance |
| none of the above. |
18.For minimum work in multistage compression, assuming same index of compression in all stages |
| work done in first stage should be more |
| work done in subsequent stages should increase |
| work done in subsequent stages should decrease |
| work done in all stages should be equal |
| work done in any stage is no criterion for minimum work but depends on other factors. |
19.The volumetric efficiency of a compressor falls roughly as follows for every 5�C increase in atmospheric temperature |
| 0.1% |
| 0.5% |
| 1% |
| 5% |
| opt 5 |
20.Losses in a centrifugal compressor are due to |
| inlet losses |
| impeller channel losses |
| diffuser losses |
| all of the above |
| none of the above |
