If the end of a tube in an exchanger is smashed, what is one of the causes?

The choice highlighting that the partition plate being too short can lead to the end of a tube in an exchanger being smashed is valid because the partition plate serves to separate different sections of the heat exchanger and support the tubes. If the partition plate is not long enough, it may not provide adequate support or alignment for the tubes, causing them to be in a vulnerable position where they can be crushed or damaged during operation or maintenance.

Additionally, a short partition plate can compromise the structural integrity of the exchanger by allowing tubes to move excessively. Movement can lead to increased stresses and potential misalignment, further increasing the risk of physical damage such as smashes or dents on the tube ends. Properly sized and installed partition plates are essential for maintaining the overall functionality and durability of the heat exchanger.
