About this file
This document is a technical calculation sheet for a water-based fire protection sprinkler system preliminary design for Project NPS HOSP (Project Number 16445000), specifically for a 2-head NFPA-13D calc for duplex configuration.
The calculations establish estimated sprinkler system demand of 54 GPM at 83.7 PSI, derived from underground piping friction losses of 13.48 PSI, elevation head loss of 15.17 PSI, and pressure loss components totaling 68.53 PSI. Supporting calculations include hazard classification (NFPA-13D), flow density requirements (0.05 GPM/SF for light hazard), sprinkler spacing specifications, and hydrant flow test data showing 0 GPM at 97 PSI and 839 GPM at 54 PSI. The document applies the Hazek Williams formula for friction loss calculations in underground piping from the city main to the fire service entrance, with detailed pipe sizing, velocity, and equivalent length computations. Elevation head loss calculations account for a 35-foot vertical rise from the starting reference elevation to the highest elevation point. The technical specifications reference NFPA 13 (2016) standards and include a pressure-demand curve graph for visualization. This preliminary design document supports water supply adequacy assessment and system component sizing for the duplex sprinkler installation.
