    in superficie

    pV=nRT

    in acqua

    p'V'=nRT'

    da cui

    V'=VpT'/(p'T)

    dove

    V=volume in superficie

    V'=volume a profondita` h

    p=pressione in superficie

    p'=p+ρgh=pressione a profondita` h [ρ=densita` acqua]

    T=temperatura in superficie

    T'=temperatura a profondita` h
