About US quarts per hour
The US quart per hour (qt/h) equals 3.785411784×10⁻³/4/3600 ≈ 2.629×10⁻⁷ m³/s, used in US agricultural irrigation drippers (emitters rated in qt/h) and hobby aquaculture systems. A drip emitter rated 1 qt/h ≈ 0.946 L/h is a common size for garden irrigation in the US market. 1 US qt/h ≈ 2.629×10⁻⁷ m³/s.
About Cubic yards per hour
The cubic yard per hour (yd³/h) equals 0.764554857984/3600 ≈ 2.124×10⁻⁴ m³/s, the standard unit for concrete pump output, earthwork compaction flow, and US dredging production rate reporting. A concrete pump truck delivers 30-80 yd³/h on a high-rise pour; a cutter-suction dredger handles 100-500 yd³/h in harbour maintenance. 1 yd³/h ≈ 2.124×10⁻⁴ m³/s.
