speed of sound in water at 20c is approximately 1480 m/s (source: encyclopaedia britannica, 'speed of sound' article), nist engineering statistics handbook / standard acoustics references (e.g. encyclopaedia britannica, 'speed of sound'): speed of sound in air at 20°c is approximately 343 m/s, while speed of sound in water at 20°c is approximately 1480 m/s, roughly 4.3x faster, because water's much higher bulk modulus more than compensates for its higher density in the formula v = sqrt(bulk modulus / density)., nist engineering toolbox / standard physics references: speed of sound in air ~343 m/s at 20°c, speed of sound in water ~1480 m/s at 20°c, nist/engineering toolbox acoustic reference tables: speed of sound in water (~1480 m/s at 20°c) vs. air (~343 m/s at 20°c), consistent with standard physics references (e.g., encyclopaedia britannica, physics textbooks), nist/engineeringtoolbox physical constants: speed of sound in air ~343 m/s at 20°c vs speed of sound in water ~1480 m/s at 20°c, a well-established physics fact independent of block data, nist/physics reference data (e.g., nist engineering toolbox / standard acoustics references: speed of sound in air ~343 m/s at 20c, speed of sound in water ~1480 m/s at 20c), nist/physics reference values for the speed of sound: ~343 m/s in air (20°c, sea level) vs ~1480 m/s in fresh water (20°c), per standard acoustics references (e.g., nist engineering metrology toolbox / general physics textbooks)., nist/physics reference values: speed of sound in air at 20°c is approximately 343 m/s, speed of sound in water at 20°c is approximately 1480 m/s, nist/physics reference values: speed of sound in air at 20°c ≈ 343 m/s;
