In the BG system, dynamic viscosity has units of pound-seconds per square foot (lb·s/ft 2), and in the EE system it has units of pound-force-seconds per square foot (lbf·s/ft 2). The pound and pound-force are equivalent; the two systems differ only in how force and mass are defined.
The Imperial gallon was based on the concept that an Imperial fluid ounce of water would have a mass of one Avoirdupois ounce, and indeed 1 g/cm 3 ≈ 1.00224129 ounces per Imperial fluid ounce = 10.0224129 pounds per Imperial gallon.
Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound, specifically a cyclic ether.It is a colorless, water-miscible organic liquid with low viscosity.
A constant blood concentration of 1 to 1.5 g/L (corresponding to 0.5 to 0.75 mg/L in the breath) should be maintained to acceptably saturate the enzyme. An initial dose of 0.6 to 0.7 g ethanol per kilogram body weight should be given (about 0.8 mL/kg or 0.013 fl.oz/lb). This will cause ethanol intoxication. To avoid adverse effects, frequent ...
Methyl acetate is produced industrially via the carbonylation of methanol as a byproduct of the production of acetic acid. [6] Methyl acetate also arises by esterification of acetic acid with methanol in the presence of strong acids such as sulfuric acid; this production process is famous [according to whom?] because of Eastman Kodak's intensified process using a reactive distillation.
The agency then calculated a "drinking water equivalent level" of 24.5 ppb by assuming a person weighs 70 kg (150 lb) and consumes 2 L (0.44 imp gal; 0.53 US gal) of drinking water per day over a lifetime. [87] [needs update]
