Though the flow pattern is affected by the roughness of the ground surface, the turbulence of the natural wind, and the configuration of the building, the author tries to get a two-dimensional solution of the pressure distribution on the wall and roof of buildings subjected to a uniform stream, such as factories with or without monitor, by the image method of the potential theory, on the assumption that the air is an ideal fluid, that is, invicid and and incompressible without temperature change, and flows along the wall and roof surfaces, with separation starting at the roof ridge. The purpose of this paper is to provide useful information on the design of the building under the wind pressure, which is easily calculated with the help of the table of modified elliptic functions attached to the end of the 2nd Part of the series of the papers to be published in the following month, though the derivation of the equations seems rather difficult due to the elliptic funcions involved. The appropriateness of this solution is verified by the experiments as presented in the successive parts of the series in special cases, although it looks reasonable at the first glance. In conclusion. the distribution of the wind pressure on the surfaces of the building, which has had so far recourse to the experiment in the wind tunnel, can be fairly estimated by this calculation method in some cases.
