In the present study, forced convection flow in two-dimensional laminar simultaneous development pipeline with rectangular geometry, is analyzed analytically using the Navier-Stokes, Poisson and Energy in its primitive form. These equations are solved by the Generalized Integral Transform Technique, which is characteristic hybrid-numeric. The development work is composed primarily by restructuring the problem, so that, it can be solved by using the subroutine Fortran, IMSL Library, DBVPFD. Then, the results obtained are considered of practical interest, such as the velocity field, the temperature profile, the behavior of the average temperature, the Nusselt number and the friction factor, with the goal of providing a better parameter for construction equipment. These parameters are assessed both longitudinally and horizontally. Finally, the results are validated through convergence charts in order to comparisons with literature articles.
