About Pound per second (lb/s)
An imperial mass-flow unit (≈ 0.453592 kg/s per NIST SP 811). lb/s is the dominant working unit in US aerospace engineering for turbomachinery: turbojet, turbofan, and turboprop engine performance data published by P&W, GE Aviation, Honeywell, and Rolls-Royce North America quote corrected and uncorrected mass flow in lb/s on type-certificate data sheets and FAR Part 33 power-plant certification documents per FAA Advisory Circular 33-2B. US-edition combustion textbooks (Glassman, Turns, Cengel & Boles) and gas-turbine engineering textbooks (Mattingly, Saravanamuttoo, Boyce) use lb/s throughout. Reference values: a GE F404 turbojet (F/A-18 Hornet) airflow ~146 lb/s at takeoff; GE9X (Boeing 777X) ~1,600 lb/s; CF6-80C2 (747-400) ~1,769 lb/s; F-1 first-stage rocket engine (Saturn V) ~5,683 lb/s of RP-1 + LOX; SpaceX Merlin 1D ~520 lb/s. Convert lb/s to kg/s by multiplying by 0.4536; to lb/hr by multiplying by 3,600; to lb/min by multiplying by 60.
About Kilogram per hour (kg/hr)
A metric mass-flow unit equal to exactly 1/3600 kg/s. kg/hr is the working unit for industrial process streams, boiler steam-output ratings (DIN EN 12952 water-tube boiler specs and EN 12953 shell-boiler specs are typically quoted in kg/hr or t/hr), petroleum refinery throughput, chemical-plant material balances (Aspen HYSYS, CHEMCAD, AVEVA SimCentral, gPROMS default unit for material-stream rates), bulk material handling, food and beverage manufacturing (production-line throughput per Codex Alimentarius), and HVAC make-up-water rates in commercial humidification systems. Reference values: a typical industrial steam boiler produces 5,000-50,000 kg/hr of saturated steam; a refinery atmospheric-crude distillation column processes 50,000-500,000 kg/hr of feed; a 100 MW gas-turbine combined-cycle gas-flow ~360,000 kg/hr air; a craft brewery's wort kettle 500-5,000 kg/hr; an espresso machine steam wand ~15 kg/hr of vapour. Convert kg/hr to lb/hr by multiplying by 2.2046; to t/hr by dividing by 1,000; to kg/s by dividing by 3,600.
