Navier-Stokes equations: a new estimate of a possible gap related to the energy equality of a suitable weak solution

Abstract: The paper is concerned with the IBVP of the Navier-Stokes equations. The result of the paper is in the wake of analogous results obtained by the authors in previous articles [4, 5]. The goal is to estimaste the possible gap between the energy equality and the energy inequality deduced for a weak solution.
