Abstract: Herein, nanotechnology efficacy on the acute velocity of fluid of fluid-conveyed-nanocomposite pipes is studied. The polymeric pipe is armed by carbon nanotubes utilising Mori and Tanaka model. The dynamic force induced by fluid is calculated utilising perturbation method. Based on method of energy and Lagrange model as well as Mindlin theory, the final equations are obtained. Utilising semi-exact solution, the relations are solved in order to calculate the acute velocity of fluid so that the efficacy of pipes geometrical constants and CNT percentage are investigated on the acute velocity of fluid. The outcomes are compared with other papers for showing the accuracy of this solution. With adding the CNT percentage, the acute velocity of fluid is improved. Indeed, the heat generation has a harmful efficacy on the acute velocity of fluid since it can reduce the acute value due to reduction in the stiffness of pipe.

Keywords: nanotechnology; acute velocity of fluid; polymeric pipes; CNT; fluid.
