5.16 P-wave estimation from measured S-wave value
 Many users will be more familiar with P-wave values as an indicator of concrete
quality.
 The P-wave velocity can be calculated directly from the S-wave velocity if the
Poisson’s ratio of the concrete is known.
Where :
V
P
= P-wave velocity
V
S
= S-wave velocity
ν = Poisson’s ratio
 If the Poisson’s ratio is known this can be entered manually.
 To simplify things, typical values for the Poisson’s ratio can be used based on
the compressive strength.
