A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
If Imperial units are used, and if torque is in pounds-force feet and rotational speed in revolutions per minute, the above equation gives power in foot pounds-force per minute. The horsepower form of the equation is then derived by applying the conversion factor 33,000 ft⋅lbf/min per horsepower:
Weight is measured in ounces and pounds (avoirdupois) as in the U.S. Volume is measured in imperial gallons, quarts, pints, fluid ounces, fluid drachms, and minims. The imperial gallon was originally defined as 10 pounds (4.5359 kg) of water in 1824, and refined as exactly 4.54609 litres in 1985.
Although not an exhaustive comparison, these claims would seem to be supported by a simple examination of the weight-to-power ratios of both models: a 225 hp Formula at a curb weight of 3,300 lb (1,497 kg) versus a 235 hp Trans Am GTA at a curb weight of 3,600 lb (1,633 kg); the weight-to-power ratio for the Formula is 14.67 lb/hp compared to ...
The average person consumes about 24 kilograms (53 pounds) of sugar each year. North and South Americans consume up to 50 kg (110 lb), and Africans consume under 20 kg (44 lb). [ 1 ]
He confirmed in his autobiography that his weight as an RAF boxer was 159 pounds (72 kg) and he was only six pounds (2.7 kg) heavier than that in 1976. [47] Shankly met his wife, Nessie, in the RAF (she was in the WAAF and stationed at the same camp) and they married in 1944.
eq < 0.60% of the cement mass, according to EN 197-1 European standard for cement, [40] or by limiting the total alkali content in concrete (e.g., less than 3 kg Na 2 O eq /m 3 of concrete for a CEM I cement (OPC)). Example of standard for concrete in Belgium: NBN EN 206 and its national supplement NBN B 15-001; [41] [42]
