In the previous paper the writer explained that when it was difficult to solve Navier-Stokes'equation directly, it was convenient to find the solution from the standpoint of minimum energy dissipation if inertia terms in the equation could be neglected. In this paper laminar flows, through straight or curved pipes with various cross-sections, were solved from this standpoint and in each case the pressure drop, velocity distribution and discharge per unit time were obtained. As to the problems of which solutions had already been found, such as the flow through a straight pipe of rectangular cross-section, it was shown that by this energy method they are solved with more easiness than by other methods.
