Original sentence: 4700 m/s.For example, for a typical steel alloy, K = 17x1010 [Pa], and  = 7700 [kg/m3], yielding a cl of.where K and G are the bulk modulus and shear modulus of the elastic materials, respectively,
Edited sentence: 6000 m/s.For example, for a typical steel alloy, K = 170 GPa, G = 80 GPa and  = 7700 kg/m3, yielding a longitudinal velocity cl of.The shear velocity cs is estimated at 3200 m/s using the same numbers.where K and G are the bulk modulus and shear modulus of the elastic materials, respectively
