Characteristics of model chains

Parameter	Symbol	Units	Values (prototype scale in brackets)
Parameter	Symbol	Units	Small chain	Large chain
Bar diameter	$d_{bar}$	mm (mm)	4 (160)	6 (240)
Mass per unit length	$m$	g/m (kg/m)	336·4 (538)	779·9 (1248)
Link length	$l_{link}$	mm (mm)	20 (800)	30 (1200)
Link width	$w_{link}$	mm (mm)	13 (520)	20 (800)
Link surface roughness (stylus profilometer, 5 mm track)	$R_{a}$	µm	1·5 (mean of several measurements, all in range 0·8–2 µm. R_a/d₅₀ = 0·01)
