Taschenbuch. Zustand: Neu. Neuware - More than forty-three million Americans, roughly one person in seven, drink water from a private well. Federal drinking-water law does not regulate a single one of them. No agency samples that water. No utility mails a report. The owner tests it, or nobody does. The same is true of the septic tank under the lawn, the storage tank in the crawl space, and the pressure switch clicking away in the basement.>Two hundred and sixteen pages across eighteen chapters cover a single property's entire water infrastructure: groundwater and well types, pumps and pressure systems, well maintenance and shock chlorination, pipe materials and fittings, tanks and cisterns, rainwater harvesting, treatment and filtration, laboratory testing, household plumbing, irrigation, greywater reuse, septic systems, emergency repairs, permits, and a seasonal calendar. It is a reference first. Key terms are defined where they matter, checklists are written to be worked from, a plain-language glossary sits at the back, and the index is built to the page rather than the chapter. What the coverage includes- The three well types, static water level, drawdown, and what each one tells you- Jet and submersible pumps, pressure tanks, and the switch settings of a healthy system- The four pipe materials you will actually meet, how each is joined, and why mixing them causes leaks- Treatment trains matched to problems: sediment, softening, carbon, iron and sulfur, ultraviolet, reverse osmosis- What to test for, how often, how to choose a lab, and how to read the result- Septic tank layers, failure signs, pumping intervals, and the licensed boundary- Burst pipes, sudden pressure loss, boil-water advisories, and a well after a flood For homeowners, property buyers, smallholders and caretakers who want one dependable shelf reference for water on their land rather than a stack of single-subject books. Nobody else is testing your water or watching your pressure. This manual is written so that you can. …

Taschenbuch. Zustand: Neu. Neuware - In 1958, a small radiation detector rode an early satellite into orbit and came back with readings nobody had expected. What they revealed was not an instrument fault. It was a belt of charged particles, trapped by Earth's magnetic field, wrapped around the planet. Every spacecraft built since has had to survive that environment, and the ones that fail to survive it usually fail quietly: a bit flipped in memory, a solar cell degraded a few percent per year, a surface eroded by atomic oxygen until its optical properties no longer match the thermal model. None of those failures announce themselves. They are budgeted for, years before launch, or they are not survived.>Sixteen chapters follow one continuous thread. A mission objective becomes a written requirement. The requirement becomes a budget of mass, power, and data. The budget is allocated to subsystems with margin. Every allocation is verified before the vehicle flies. Inside the book: - How to choose a shielding thickness against a total-dose requirement, and why shielding does comparatively little against the effects that flip a single bit- What a spacecraft's thermal cycle count actually reaches over a six-year mission, and what that number does to a mechanism- How to estimate end-of-life solar array power once radiation damage has been accounted for- Why a spacecraft with eight subsystems that each meet their written specification can still fail its mission- The full delta-v arithmetic behind a transfer to geostationary orbit, and the propellant mass it costs in kilograms- How to close a radio link budget in decibels, and which term to change first when it will not close- The one question to ask before adding a redundant unit Every chapter opens with learning objectives, defines its vocabulary where it is first needed, and ends with practice problems and an answer key, so a method can be exercised rather than only read. Written for engineers moving into spacecraft work from another discipline, graduate students who need the numbers behind the block diagrams, and subsystem specialists asked to hold the whole vehicle in view.…
