Final answer:
A reference to a negative pressure of about 344 lb/in² suggests the significance of high pressures in specific engineering applications.
Explanation:
The question about the pressure limit to pump water into the tank of P-23 revolves around understanding the maximum safe operating pressure for a specific system or component, which is a key aspect in the field of engineering.
However, based on the information provided in the reference texts, a comparison can be made. A negative pressure of 25.0 atm is mentioned as being achievable before water separates, and this equates to around 344 lb/in² (or 23.7 atm), hinting that pressures in certain systems can indeed reach high values safely.
