rhe effective Hamiltonian method is used to find the distribution functiondescribing the positions as a function of time of a given pair of fluid particlessubject to convection in steady, incompressible, statistically isotropic turbulentflow. By assuming a joint Gaussian distribution for the velocity field, a reasonabletime dependence is obtained for the statistical average of the distance between thepair of fluid particles. The basis for Richardson's four-thirds law is indicated andthe proportionality constant C' is shown to be related to the Kolmogorov con-slant C by C'=3"'C""/2"'
