Paperback. Condition: new. Paperback. Propulsion engineering spans an unusually wide range of physical regimes, from the subsonic inlet flow of a turbofan on approach to landing, through supersonic and hypersonic flight, to the near-vacuum environment where an electric thruster can operate for months at a time. Most readers meet these as separate subjects, taught in different courses, with no shared notation between them. That separation creates a real gap. A reader who has just worked through a compressor stage in one course and a rocket nozzle in another often has no way to see that both problems rest on the same compressible-flow equations and the same thrust equation, applied twice rather than derived once. Textbooks that hand over finished formulas without their derivation make the gap worse, since a memorized formula offers no way forward when a real design problem does not match the textbook case. This sixteen-chapter guide treats propulsion engineering as one connected subject rather than as separate topics in aircraft engines and rocket engines. Every governing equation, from the steady-flow energy equation to the rocket thrust equation, is derived from stated assumptions, and every numerical example carries consistent units, in SI and US customary systems, from the given data to a final boxed answer. Inside, readers will: Follow every major equation from its stated assumptions through a full derivation, rather than accepting a boxed formula without justification.Build one connected framework for compressible flow, stagnation properties, and the thrust equation, applicable across gas-turbine and rocket systems alike.Move component by component through a complete gas-turbine engine, from inlet and compressor through combustor, turbine, and nozzle, before assembling those components into turbojet, turbofan, turboprop, and turboshaft cycles.Apply the thrust equation to compute gross thrust, net thrust, propulsive efficiency, thrust-specific fuel consumption, and specific impulse for realistic flight conditions.Extend the same reasoning into high-speed ramjet and scramjet propulsion, and into chemical rocket propulsion, propellants, and combustion.Explore emerging electric and advanced propulsion concepts, including ion and Hall-effect thrusters, nuclear thermal rockets, and solar sails.Check understanding against practice problems at the end of every chapter, each paired with a worked, boxed answer.Key topics: thermodynamic and gas-dynamic foundations; the thrust equation and propulsive, thermal, and overall efficiency; Brayton-cycle analysis and real-cycle losses; inlet, compressor, combustor, turbine, and nozzle behavior; turbojet, turbofan, turboprop, and turboshaft cycle performance; ramjet, scramjet, and afterburning propulsion; chemical rocket propulsion and propellant combustion; electric and advanced propulsion systems; and the integration and testing practices that connect analysis to flight hardware. This book is written for the upper-level mechanical or aerospace engineering student encountering propulsion systems for the first time in a structured course, and for the practicing engineer who needs a rigorous, well-organized reference for cycle analysis, component behavior, or rocket propulsion fundamentals. Its consistent notation and self-contained chapters make it equally useful as a course companion and a standing reference. Take the next step toward a clearer, more connected understanding of propulsion engineering: add this comprehensive, derivation-based guide to your library and begin working through the equations, examples, and component-by-component reasoning the subject demands.

Paperback. Condition: new. Paperback. A technician who has only memorized symptoms will always be limited to matching a new fault against a mental list of old ones. A technician who understands why the equipment behaves as it does can diagnose a system they have never seen before, and explain that diagnosis in terms a supervisor or a customer can follow. Most commercial refrigeration knowledge is picked up in fragments: superheat learned on one job, oil return figured out on another, defrost logic passed along secondhand by a coworker who half-remembers it. That patchwork holds up fine until a fault doesn't match anything already seen, and then diagnosis turns into guesswork, parts get swapped that never needed replacing, and the same callback comes back. This handbook builds commercial refrigeration knowledge the way a technician actually encounters it in the field: starting with the thermodynamic cycle every system shares, moving through each major component in working depth, applying that knowledge to the complete equipment types serviced day to day, and closing with the diagnostic, maintenance, and regulatory knowledge the job demands every day. What you'll gain: Understand the vapor-compression cycle well enough to read a pressure-enthalpy diagram and interpret gauge readings as a coherent physical story, not a checklistWork confidently across compressors, condensers, evaporators, and metering devices, recognizing how each component's failure shows up in field readingsSize and select piping, accessories, and electrical controls using the same reasoning developed throughout the book, reinforced with worked examples that show every step and unitApply component-level knowledge to complete system types: reach-in and walk-in equipment, supermarket rack and multiplex systems, ice machines, and specialty equipmentChoose and troubleshoot defrost strategies appropriate to the application and climateFollow a structured diagnostic method that uses superheat, subcooling, and pressure-temperature relationships to narrow a fault before parts are ever pulledBuild and document a preventive maintenance program that protects capacity and efficiency instead of reacting to failuresKey topics covered: refrigerant properties and safety classification, current regulatory compliance requirements, compressor and condenser selection, evaporator and metering-device operation, refrigeration piping and electrical controls, reach-in and walk-in box load calculation, supermarket rack and multiplex architecture, ice machine and specialty equipment operation, defrost system design, installation and startup procedures, structured troubleshooting, preventive maintenance planning, and energy-efficiency and safety practices. Who this book is for: working commercial refrigeration and HVAC/R service technicians who want to diagnose by understanding rather than by pattern-matching; apprentices and trade-school students building a systematic foundation; residential or light-commercial technicians moving into commercial and supermarket refrigeration work; and service managers looking for a consistent reference to train and standardize a crew.Add a single, connected reference to the toolbox, and start replacing guesswork with a diagnostic method built on how the equipment actually works.

Paperback. Condition: new. Paperback. A metal part behaves almost the same on day one and ten years later, provided it isn't corroding. A polymer part almost never does. Its stiffness shifts with temperature, it creeps under a load a metal would carry indefinitely, and it can turn brittle years into service with no visible warning, because heat, oxygen, ultraviolet light, or moisture have been quietly reworking its molecular structure the whole time. An engineer who treats a polymer data sheet the way a metal data sheet is treated, as a fixed set of numbers good for the life of the part, eventually gets surprised by it, usually as a field failure, a warped molded part, or a fitting that cracked far below its rated strength. Much of the available material on polymers doesn't close that gap, because it specializes: a chemistry-focused text stops short of manufacturing, a processing manual treats material behavior as a black box, and a design guide offers rules of thumb without showing where the numbers came from. This book follows a single connected thread instead, from a polymer's molecular architecture through its measurable properties, through the processes that convert resin into product, to the design decisions an engineer must ultimately defend, with every relationship derived from first principles and demonstrated on a fully worked, unit-checked numerical example. Inside, you will: Derive and apply the governing relationships for polymerization kinetics, crystallinity, melt viscosity, and viscoelastic response, each demonstrated on a complete, checked numerical example.Learn to read a calorimetry thermogram, a melt-flow-index result, and a dynamic mechanical analysis sweep well enough to translate them into an actual processing window.Compare commodity and engineering thermoplastics, thermosets, elastomers, and specialty polymers on the properties that genuinely decide a material selection.Predict fiber-reinforced composite stiffness with the rule of mixtures and a second, more broadly applicable stiffness model, and size an extrusion screw, an injection mold's clamp force and cooling time, or a thermoformed part's wall thickness.Apply creep-adjusted modulus, fatigue behavior, and stress-concentration principles to size a snap-fit joint, a living hinge, or a reinforcing rib for years of real service rather than a single laboratory test.Coverage runs from polymerization mechanisms and molecular weight distribution through morphology and crystallinity, thermal and rheological characterization, mechanical and viscoelastic behavior, degradation and long-term lifetime prediction, the major thermoplastic, thermoset, elastomer, and specialty polymer families, additive formulation, fiber-reinforced composites, extrusion, injection molding, thermoforming and blow molding, polymer additive manufacturing, mechanical design for polymer components, and systematic material selection and sustainability. This book is written for the reader who already has an engineering foundation and now needs a genuinely quantitative treatment of polymers: an upper-level engineering student, or a practicing mechanical, materials, chemical, or manufacturing engineer who needs a dependable reference for material, process, and design decisions involving plastics, elastomers, and composites. Take the next step toward understanding and applying the ideas presented in this comprehensive guide, and start building a quantitative command of polymer behavior that a data sheet alone cannot provide.
