About these units
Foot/Minute (ft/min)
A foot per minute is common in industrial engineering, HVAC air flow analysis, elevator design, and manufacturing processes. Ventilation rates in ducts are often reported in ft/min, making the unit crucial for designing safe and comfortable living spaces. In machining, ft/min corresponds to cutting speed along a tool edge, helping determine tool wear and material removal rates. Despite being less familiar in daily life, ft/min is a key engineering unit.
Speed of Sound in Sea Water (vₛₑₐ)
In sea water, the speed of sound is generally higher—around 1,530–1,540 m/s—due to dissolved salts, temperature gradients, and pressure at depth. Sea water's complex structure causes refraction of sound waves, creating deep sound channels (like the SOFAR channel) that allow sound to travel vast distances with minimal attenuation. Oceanographers use sound-speed profiles to map underwater topography, measure ocean temperatures, and study global climate patterns. The speed of sound in sea water is essential for both marine ecology and military navigation.
