In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
1.51% (1 in 66) – (1 foot (0.3 m) per 1 chain (20 m)) New South Wales Government Railways, Australia, part of Main South line. 1.25% (1 in 80) – Wellington Bank, Somerset , UK 1.25% (1 in 80) – Rudgwick , UK ( West Sussex ) platform before regrading – too steep if a train is not provided with continuous brakes .
Originally the sensitivity was written as a fraction with 'tenths' (for example "18/10° DIN"), [16] where the resultant value 1.8 represented the relative base 10 logarithm of the speed. 'Tenths' were later abandoned with DIN 4512:1957-11, and the example above would be written as "18° DIN". [ 7 ]
To convert heat values to joules per mole values, multiply by 44.095 g/mol. To convert densities to moles per liter, multiply by 22.678 cm 3 mol/(L·g). Data obtained from CRC Handbook of Chemistry and Physics , 44th ed. pages 2560–2561, except for critical temperature line (31.1 °C) and temperatures −30 °C and below, which are taken from ...
In 2016, the United States was downgraded from a full democracy to a flawed democracy; [9] its score, which had been declining for some years, crossed the threshold from 8.05 in 2015 to 7.98 in 2016. The report stated that this was caused by myriad factors dating back to at least the late 1960s which have eroded Americans' trust in governmental ...
In that year, the industrial sector consumed about 42.2% of the electricity, with the residential sector consuming nearly 26.8%, the commercial and public services sectors consuming about 21.1%, the transport sector consuming nearly 1.8%, and the other sectors (such as agriculture and fishing) consuming nearly 8.1%.

Attenuation is governed by the Beer-Lambert Law, namely that the transmittance or fraction of insolation reaching the surface decreases exponentially in the optical depth or absorbance (the two notions differing only by a constant factor of ln(10) = 2.303) of the path of insolation through the atmosphere. For any given short length of the path ...
