Studies on the resistance to the flow of water in curved pipes and pipe bends

Abstract

This thesis contains the theoretical and experimental investigations carried out by the author on the resistance offered to the flow of water curved curved pipes and pipe bends The thesis is in three parts In Part I » a comprehensive review of the present status of knowledge on the subject is made. This part is entitled as "Literature Survey" and constitutes part of the library research conducted. In Part III , the analytical investigations carried out by the author are presented. In Part I I I , the experimental investigations carried out in order to confirm the validity of the analysis presented in Part I I are described. In addition, some theoretical conclusions are checked with data already available from other sources. Rational formulae for computing the loss of pressure head have been put forth, based on the theoretical and experimental investigations conducted. It is hoped that these formulae may be of utility to the practicing engineer. Regions in which further investigations are necessary have been indicated in a problem in which the yet unsolved problems of turbulence, separation phenomena, and three-dimensional boundary layer flow are involved
