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:$Q = K \cdot \sqrt{P}$Q=K⋅P​(where$Q$Qis flow rate,$K$Kis sprinkler coefficient, and$P$Pis pressure).

Consider Safety Margins:

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