| Q. |
Internal cavitation in reciprocating pumps occurs due to |
| A. | drag force |
| B. | cyclic stress |
| C. | shock waves |
| D. | flow speed |
| Answer» C. shock waves | |
| Explanation: at high pressure, the voids can generate shock waves. cavitation usually occurs due to the changes in pressure. the pressure change is so rapid that it leads to formation of liquid free layers or cavities that start to affect the overall performance. | |
