Abstract
THE volume before us gives some of the first results obtained in the four-foot wind tunnel which has been erected at the Massachusetts Institute of Technology, and consists of ten sections dealing with various phases of the work. The first section gives a detailed description of the wind tunnel, the design of which is practically identical with that of the four-foot tunnel at the National Physical Laboratory, Teddington. This is followed by a discussion of the dimensional theory as applied to aerodynamic problems. The theory is treated in a simple and easily followed manner, but due credit has not been given to Lord Rayleigh, who first proposed the theory in this form. Lord Rayleigh is mentioned, however, in this connection in a later section of the book. Section 3 deals with the inclined tube alcohol manometer for measuring small pressure differences. The results of the calibration of such an instrument against a standard Chattock manometer are given. The inclined tube instrument certainly has no advantages over the Chattock form, and experience at the National Physical Laboratory shows that the latter is exceedingly convenient for use. The theory of the pilot tube is considered, and experimental results are appended to show that several types of combined pitot and static pressure tubes give identical calibrations.
