 · Two Rules-of-Thumb Regarding Piping Systems. Have you noticed, looking at the famous ASME B31.1 support spacing Table 121.5, that the spacing between pipe supports is roughly "size + 10", in other words, the spacing between supports on an 1 inch instrument tubing would be "1 + 10" = 11 ft, while the spacing on a 6 inch line for example ...

Origin and usage. In English, rule of thumb refers to an approximate method for doing something, based on practical experience rather than theory. The exact origin of the phrase is uncertain. Its earliest (1685) appearance in print comes from a posthumously published collection of sermons by Scottish preacher James Durham: "Many profest Christians are like to foolish builders, who build by ...

Moore''s law is the observation that the number of transistors in a dense integrated circuit (IC) doubles about every two years. Moore''s law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production.. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and ...

Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold jection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.

For example, if a property was producing $200 a month ...

 · The general rule of thumb is that the value of a mineral deed is about two to three times larger than the value of a mineral lease. So, if the current going rate for leasing minerals in an area is $1,000/acre (say, with a 15% royalty rate), then the value for outright selling those mineral rights should be between $2,000/acre and $3,000/acre.

 · In this rule of thumb, we discuss the importance of melt uniformity in injection moulding. In a previous rule of thumb, we showed that there is a 20% variation in viscosity due to the intrinsic polymer structure (here thefull post).Additionally, non-molten plastic pellets and non-uniformity of melt can cause several more problems in the final part.
