22. A vertical profile perpendicular to the crest line of an asymmetrical ripple is given in the figure. The calculated ripple index is……….. Ripple index = (Wavelength) / (Height) Wavelength = Stoss length + Lee length = (40 + 200) mm = 240 mm Height = 60 mm So, Ripple index = 240 mm / 60 mm = 4 (An...
