Heat Exchangers: Selection, Rating, and Thermal Design
د.إ450.00Heat exchangers are essential in a wide range of engineering applications, including power plants, automobiles, airplanes, process and chemical industries, and heating, air conditioning and refrigeration systems. Revised and updated with new problem sets and examples, Heat Exchangers: Selection, Rating, and Thermal Design, Third Edition presents a systematic treatment of the various types of heat exchangers, focusing on selection, thermal-hydraulic design, and rating.
Topics discussed include:
- Classification of heat exchangers according to different criteria
- Basic design methods for sizing and rating of heat exchangers
- Single-phase forced convection correlations in channels
- Pressure drop and pumping power for heat exchangers and their piping circuit
- Design solutions for heat exchangers subject to fouling
- Double-pipe heat exchanger design methods
- Correlations for the design of two-phase flow heat exchangers
- Thermal design methods and processes for shell-and-tube, compact, and gasketed-plate heat exchangers
- Thermal design of condensers and evaporators
This third edition contains two new chapters. Micro/Nano Heat Transfer explores the thermal design fundamentals for microscale heat exchangers and the enhancement heat transfer for applications to heat exchanger design with nanofluids. It also examines single-phase forced convection correlations as well as flow friction factors for microchannel flows for heat transfer and pumping power calculations. Polymer Heat Exchangers introduces an alternative design option for applications hindered by the operating limitations of metallic heat exchangers. The appendices provide the thermophysical properties of various fluids.
Each chapter contains examples illustrating thermal design methods and procedures and relevant nomenclature. End-of-chapter problems enable students to test their assimilation of the material.

Currency Wars II: The Power of Gold
د.إ140.00The structure of any human society is a typical pyramidal one, with a critical minority of people gradually moving up through the social structure due to their own intelligence and diligence, and in some cases through violence and fraud. When they have sufficient financial power and influence, they will in turn consolidate and expand their vested interests by changing the rules of the game and creating a ruling elite with interlocking interests. If the power pyramid structure of Eastern societies is based on regimes, the Western pyramid of domination is a chain of very hidden debts that hold the various strata of society firmly together. In Western societies, creditors have dominant power and debtors are in a dominated position, and the main function of the state apparatus is to protect and reinforce the reliability of this chain. In the West, whoever is the biggest creditor is the ultimate lawmaker of the game, and central banks, controlled by international bankers since the 19th century, are undoubtedly the biggest creditors of society as a whole, with the rest of society, including governments, being their debtors. From this perspective, the West today is actually a financial powerhouse controlling government decisions.
This book will comprehensively describe the formation, development, exclusion, conflict, alliance and checks and balances of the major financial power groups in Europe and the United States over a period of 300 years, systematically analyze the operation and decision-making mechanism of the dominant forces behind the scenes in the world today, and for the first time unveil the mystery of the “international banking family club” that rules the world.
