Pumps are widely used in industries either to circulated fluid or pressurize fluid according to requirements. The performance analysis of pump is very important as these are used in large number in process and other industries. Considering importance of pump performance, various methodologies available in literature analyzed using experimental data and from it the best method is proposed. The best method proposed will give efficient performance, which results in large amount of energy saving considering utilization of pumps widely across all area. This book will be definitely useful for those which are working in the area of centrifugal mainly engineering students who are learning pumps, practitioner engineers, pump designers, etc.
