Kitchen Range Hood Exhaust Aerodynamics, Capture Velocity, and Make-Up Air Sizing Benchmark Matrix
Computational capture-efficiency matrix for residential and light-commercial kitchen range hoods under IRC Section M1503.6 and ASHRAE Standard 62.2. Models thermal plume buoyant velocity, total equivalent length (TEL) static pressure loss compensation, and mandatory make-up air interlock thresholds.
đŦ Dataset Methodology & Engineering Basis
Calculates exhaust airflow requirements across gas, electric, and induction cooktops. Gas burner output is sized at 1 CFM per 100 BTU/h, electric/induction cooktops at 10 CFM per linear inch of width, with island hood multiplier (1.33x) and ACCA Manual D equivalent duct length static friction adders. Make-up air interlocks are flagged for systems exceeding 400 CFM per IRC M1503.6.
