The London Science Museum's difference engine, the first one built from Babbage's design. It has the same precision on all columns, except in calculating polynomials, the precision on the higher-order columns could be lower. A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.
In mathematics, divided differences is an algorithm, historically used for computing tables of logarithms and trigonometric functions. [citation needed] Charles Babbage's difference engine, an early mechanical calculator, was designed to use this algorithm in its operation.
Between 1995 and 2000, cars using this 3.0 L engine formula, imposed by the FIA, produced a constant power range (depending on engine type and tuning), varying between 600 hp and 815 hp. Most Formula One cars during the 1997 season comfortably produced a consistent power output of between 665–760 hp (495.9–566.7 kW), depending on whether a ...
The efficiency of internal combustion engines depends on several factors, the most important of which is the expansion ratio. For any heat engine the work which can be extracted from it is proportional to the difference between the starting pressure and the ending pressure during the expansion phase.
The mean effective pressure (MEP) is a quantity relating to the operation of a reciprocating engine and is a measure of an engine's capacity to do work that is independent of engine displacement. [1] Despite having the dimension of pressure, MEP cannot be measured. [ 2 ]
One should not confuse thermal efficiency with other efficiencies that are used when discussing engines. The above efficiency formulas are based on simple idealized mathematical models of engines, with no friction and working fluids that obey simple thermodynamic rules called the ideal gas law. Real engines have many departures from ideal ...

If other units are used, the constant is different. When using coherent SI units (watts, newtons, and metres per second), no constant is needed, and the formula becomes P = Fv. This formula may also be used to calculate the power of a jet engine, using the speed of the jet and the thrust required to maintain that speed.
