bhp meaning in oil and gas

Horsepower vs "Brake HorsePower"<p> 1) "The definition of 1 horsepower is the ability to raise 550 pounds 1 foot high in 1 second. Another way of saying that is "550 foot-pounds per second". <p> <p> "Brake horsepower" is the vehicle's horsepower measured where the power is delivered (for example, at the rear axle of a truck tractor. Shaft horsepower is the power measured at the engine itself, before any losses from the clutch or differential occur." <p> <p> You can measure brake horsepower wherever you like, manufacturers usually quote it at the flywheel, which gives the biggest answers. Rally people usually measure it at the wheels because that's the output a rolling road gives, then the operator gives his view on an adjustment to give a flywheel reading depending on car configuration, weather etc. <p> <p> <p> ---------------<p> 2) “Brake” is added to Horsepower to show that the measurement of power is done by using a brake on the engine. The measurement can be done according to different standards: <p> <p> DIN (Deutsche Institut fur Normung): widely used by European manufacturers. <p> ECE (Economic Commission for Europe), ISO (International Standardization Organization): these two are very similar to (and slowly replacing) the DIN-standard. <p> SAE (Society of Automotive Engineers): American standard, nowadays used only for the American market, but in the past also used in Europe. <p> JIS (Japanese Industrial Standard): Japanese standard, used only for the home market. For export markets Japanese manufacturers use the local standard: DIN for Europa, SAE for Amerika. <p> <p> For JIS and SAE measurements some major applications to the engine may be disconnected (like alternator, exhaust system, engine cooler), while with the DIN/ECE/ISO standard those application cannot be disconnected. Because of this there will always be a 10 to 20 % difference between a JIS/SAE and DIN/ECE/ISO measurement for the same engine, with JIS/SAE of course showing the higher output value. <p> <p> Power of an engine should nowadays be put in Kilowatt (kW) instead of non-SI units like HP. <p> There is a small difference between the European and Anglo/American HP, caused by the use of different units. (Europe: kilos and meters, England: inches and pounds). <p> <p> 1 Euro-HP = 0.9862 Anglo-HP <p> (or 1 Anglo-HP = 1.0139 Euro-HP) <p> 1 kW = 1.35962 Euro-HP <p> (or 1 Euro-HP = 0.7355 kW) <p> <p> <p> <p>
