This is a process diagram of a turbine generator. Engineers working to produce a sustainable process for use in the chemical industry need to know how to design a sustainable process in which the system can withstand or manipulate process-halting conditions such as heat, friction, pressure, emissions, and contaminants.
Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations.The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.
Tort law and product liability impose additional costs on manufacturing. These are significant dynamics in the ongoing process, occurring over the last few decades, of manufacture-based industries relocating operations to "developing-world" economies where the costs of production are significantly lower than in "developed-world" economies.

The decimal nature of these units and of the device made it easy to calculate the area of a rectangle of land in acres and decimal fractions of an acre. [5] Having difficulties in communicating with German scientists, the Scottish inventor James Watt, in 1783, called for the creation of a global decimal measurement system. [6]
Magnetic storage technologies are being developed to address this trilemma, and compete with flash memory–based solid-state drives (SSDs). In 2013, Seagate introduced shingled magnetic recording (SMR), [ 84 ] intended as something of a "stopgap" technology between PMR and Seagate's intended successor heat-assisted magnetic recording (HAMR).
Share of adults that are obese, 1975 to 2016. Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.

The original design of the heavy-lift Ares V, named in homage to the Saturn V, was 360 feet (110 m) in height and featured a core stage based on the Space Shuttle External Tank, with a diameter of 28 feet (8.4 m). It was to be powered by five RS-25 engines and two five-segment Space Shuttle Solid Rocket Boosters (SRBs).
