Assess Building Water Demand:

• Use hydraulic calculations based on sprinkler and hose demands.

Reference NFPA Guidelines:

• Follow NFPA 13, 14, and 20 to determine flow rate and pressure.

Use Formula-Based Calculations:

• For example: $Q = K \cdot \sqrt{P}$ (where $Q$ is flow rate, $K$ is sprinkler coefficient, and $P$ is pressure).

Consider Safety Margins:

• Add a buffer to ensure the pump meets peak demand.
