The finite difference equations of fully developed fluid flow and heat transfer in a rectangular pipe are established, and the corresponding computer program is compiled to solve the velocity and temperature on grid nodes in pipe cross section. Then the equivalent-temperature lines of velocity and temperature are automatically drawn by graphic display algorithm. Finally, the characteristics of velocity and temperature of heated fluid flow in pipes are discussed.
