The inlet flow rate requirements for fire pumps depend on several factors, including the specific application, local building codes, and the standards established by organizations such as the National Fire Protection Association (NFPA) in the United States. The NFPA Standard 20, "Standard for the Installation of Stationary Pumps for Fire Protection," provides guidelines for the installation and operation of fire pumps. However, these recommendations may vary based on regional regulations and standards.

The term "fire pump shrinkage" is not commonly used in standard technical language related to fire pumps. However, based on the context, I assume you might be referring to a situation where a fire pump experiences a decrease in performance or efficiency over time. If this is the case, several factors can contribute to a decline in the effectiveness of a fire pump:

If a fire pump is used for an extended period without proper maintenance and monitoring, various failures and issues may arise. Here are some common failures that can occur over time:
