 DENSITY, g/cm3 



Figure 14. A summary of compressional wave velocity versus density in Hamilton (1977). 

 The general curves of ND and G are included for comparisons. The equation for the curve 

 of Gardner et al (1974, p 779) is p = 0.23 Vp^-^^; where p is density in g/cm^ and Vp is 

 compressional wave velocity in feet per second.
