Preface

Abstract

The treatment of the subject of Fluid Mechanics in the present Division is intended to furnish a relatively simple and “easy reading” introduction to those parts of the subject of special interest to the student of aerodynamics. For the proper understanding of the various monographs which make up this presentation of the general subject of Aerodynamic Theory, there will be needful some familiarity with the subject of Fluid Mechanics beyond, or at least somewhat different from that gained by the student in the courses found in most of our technical colleges and schools. To many others, to whom these matters have been familiar at one time, facility, through disuse, may have been lost.
