In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2.
For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
Honda has made a number of naturally-aspirated V12 engines designed for Formula One motor racing; starting with the 1.5-litre RA271E engine in 1964, [10] [11] and ending with the 3.0-litre RA273E in 1968. [5] [12] This would be followed by a 21-year hiatus, until Honda reintroduced the new 3.5-litre RA121E in 1991. [13]
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
The wing has an active aero flap, and contributes to a total maximum downforce of more than 400 kg (882 lb) at 249 km/h (155 mph). The Michelin Pilot Cup 2 R tires are specific to the car, and are available in M01A soft and M02 hard compounds.
Each elevator could carry about 600 pounds (270 kg) (roughly the weight of two lions) 23 feet (7.0 m) up when powered by up to eight men. [4] In 1000, the Book of Secrets by Ibn Khalaf al-Muradi in Islamic Spain described the use of an elevator-like lifting device to raise a large battering ram to destroy a fortress.
