Hans D Baumann – författare

Hans D. Baumann, has almost fifty years of business experience analyzing the organizational structure & internal workings of hundreds of companies &, as a result, has reached some startling conclusions as to the major influences affecting their profitability.Ever wonder why large corporations become less profitable? Or, why old established companies such as General Motors & Delta Airlines seem to go out of business? Are larger companies really more efficient than their smaller brethren? What does a high price to earning ratio really tell you about the operating efficiency of a company? Is it a good idea to hold on to the shares of a company after a merger has been concluded? Does it pay to split-up a company? What is the relationship between the organization of the US Army and corporate hierarchy? Why do most business mergers fail?You will find answers to these & other questions, given in a plain & sometimes humorous manner, in the book, "Building Lean Companies: How to Keep Companies Profitable as They Grow."

This up-to-date work on final control elements presents theoretical and practical information in an easy, conversational style, which makes it an excellent reference for experienced instrument and process engineers as well as students who are new to the field.The book begins with a basic explanation of the function and purpose of control valves, explaining the various types of valves that are available along with their features and limitations. It also provides:Directions for selecting the best valve for a given service and the right flow characteristicsSimplified equations for sizing control valves for liquids and gases under normal and special conditions, such as flashing and laminar flowDirections for minimizing environmental problems, such as noise produced by turbulent or cavitating fluids and aerodynamic noiseSolutions to dynamic instability problemsMethods for improving control loop stabilityDiscussion on related safety issues such as “fail-safe” action and cybersecurityMany reference tables provide information that will be invaluable in valve selection, such as valve materials, temperature ratings, and valve dimensions. Also, for the benefit of international readers, examples and equations are presented in metric as well as U.S. customary terms and measurements.
