Taschenbuch. Condition: Neu. Neuware - Most books on orbital motion fall into one of two traps: some are elegant enough to admire but never actually compute an answer, while others hand you formulas to apply but never show where they came from. Spaceflight demands both, the derivation and the number.If you are studying or working in astronautics, you have felt the gap. A lecture builds a beautiful equation; the problem set then asks for a result in kilometers per second, and the path between the two is left to you. Notation drifts from chapter to chapter, and worked examples skip the exact steps where you are stuck. You can recite the theory but hesitate when it is time to produce a number you can trust.This handbook is written to close that gap. It derives each result honestly from first principles and carries it all the way to a worked number, in SI units, that an engineer could actually use. Every assumption is stated, the notation is fixed once and reused everywhere, and each calculation is shown step by step, units included, so you can move confidently from concept to answer.Inside, you will: - Understand where each equation comes from, through complete derivations rather than quoted results.- Work fully worked SI examples that show every step, then test yourself on practice problems with boxed answers and a full appendix of solutions.- Describe any orbit with its elements, locate a body on it at any time, and determine an orbit from observations.- Plan maneuvers, transfers, plane changes, phasing, and rendezvous, and estimate their velocity cost.- Design interplanetary trajectories, size launch windows, use gravity-assist flybys, and account for the perturbations that reshape real orbits.- Propagate an orbit numerically when no formula suffices, and estimate rocket performance and launch requirements.Key Topics: reference frames and time; the two-body problem and orbital elements; position versus time; orbit determination; impulsive maneuvers and transfers; relative motion and rendezvous; the two-point transfer problem; interplanetary trajectories and gravity assists; orbital perturbations and decay; numerical propagation; rocket performance and launch; and the restricted three-body problem with its libration points.Who it is for: It is written for upper-level undergraduate and early graduate students in aerospace and mechanical engineering, and for practicing engineers who want a rigorous refresher. It assumes calculus, vectors and matrices, and elementary particle dynamics, and builds everything particular to orbits from there.Open the book and begin developing the knowledge to approach any orbit problem with clarity and confidence, from the first derivation to the final number.…

Paperback. Condition: new. Paperback. Turn HVAC theory into buildings that actually perform. Every HVAC design begins with a simple demand and a hard reality: keep indoor air comfortable, healthy, and efficient while the weather outside swings by tens of degrees - and an equation you cannot run on real numbers is one you do not truly own. Thermodynamics, fluid mechanics, heat transfer, controls, human comfort, and building codes all press on a single design decision at once, usually while a schedule runs. Many references stop at tidy theory or hand over rules of thumb without the reasoning, leaving engineers to bridge the gap between the classroom and a commissioned building alone. This handbook closes that gap. It develops every method from first principles and carries it through complete, unit-tracked calculations - from the physics of a single air process to a fully commissioned, maintainable system - so you can execute the work, not just recognize it. Inside, you will: Build integrated fluency that links comfort targets, load calculations, equipment selection, and control logic instead of treating them as separate subjects. Follow fully worked examples that show every step, with end-of-chapter practice problems and boxed answer keys to check your own work. Calculate loads, size and select equipment, and lay out air and water distribution with methods you can apply directly to your projects. Analyze refrigeration cycles, chilled-water plants, and heat-pump systems, and read the performance numbers that separate an efficient design from a wasteful one. Design and sequence controls, then quantify energy use, life-cycle cost, and efficiency savings in defensible terms. Work in both inch-pound and SI units, following current United States practice throughout. Carry a design through ventilation, commissioning, testing and balancing, and troubleshooting - where real buildings succeed or fail. Key topics: thermal comfort and psychrometrics; envelope heat transfer and heating and cooling load calculations; refrigeration cycles, refrigerants, and the low-GWP refrigerant transition; duct design, fans, and pumps; boilers, hydronics, and radiant heating; chilled-water plants and cooling towers; ventilation, filtration, and indoor air quality; air-handling units and terminal equipment; controls and building automation; energy efficiency and life-cycle cost; heat pumps and emerging low-carbon technologies; and whole-system design integration, commissioning, and maintenance - supported by extensive reference appendices and a complete building design example. Who it is for: practicing mechanical and building-services engineers, engineers moving into HVAC from adjacent fields, and advanced engineering students who have completed introductory thermodynamics and fluid mechanics. Read in sequence it works as a course; consulted by chapter, it serves as a dependable working reference. Open the handbook and start building the integrated, calculation-ready understanding that turns HVAC theory into buildings that perform. This item is printed on demand.
