About Pound per hour (lb/hr)
An imperial mass-flow unit dominant in US HVAC, boiler and steam-engineering work, petroleum refining, and chemical process plants. Boiler capacities in the US are traditionally rated in lb/hr of steam output (e.g., "500 horsepower boiler" ≈ 17,250 lb/hr of saturated steam). Fuel consumption on large engines and turbines is frequently quoted in lb/hr.
About Pound per second (lb/s)
An imperial mass-flow unit used in US aerospace engineering, combustion analysis, and some heavy-industry process engineering. Turbojet engine specification sheets and US-edition combustion textbooks commonly use lb/s for air and fuel flow. 1 lb/s ≈ 0.454 kg/s.
