📊 System Loss Breakdown Estimator

Calculate the total required static pressure (P_{s, total}) by summing friction and dynamic losses.

1. System Base & Duct Input

Total Design Airflow (Q_total)

Air Density (ρ)

Total Equivalent Duct Length (L)

Representative Duct Diameter (D_eq)

2. Component Dynamic Losses (Local Losses)

Input the K-factor (loss coefficient C) for each major component. P_local = K ⋅ P_v.

Note on Calculation: This tool uses the Darcy-Weisbach friction loss formula based on a simplified constant friction factor (f=0.02). Dynamic losses are calculated as the sum of all component K-factors multiplied by the Dynamic Pressure (P_v). **Accurate calculation requires using the hydraulic equivalent diameter and detailed K-factors for all components.**
