Brake mean effective pressure (BMEP) is calculated from measured dynamometer torque. Net indicated mean effective pressure (IMEP) is calculated using the indicated power; i.e., the pressure volume integral in the work per cycle equation. Sometimes the term FMEP (friction mean effective pressure) is used as an indicator of the mean effective ...
The brake balance or brake bias of a vehicle is the distribution of brake force at the front and rear tires, and may be given as the percentage distributed to the front brakes (e.g. 52%) [1] or as the ratio of front and rear percentages (e.g. 52/48). [2]

Brake fluid is mainly used on brake systems, but is also widely used for hydraulically controlled clutches. [25] Depending on the application, the fluid is subjected to different pressures: in the case of motorcycles, it has pressure peaks that range from 8 to 15 bar, while in Formula 1 cars it exceeds 75 bar.

Brake horsepower per cubic centimeter or (bhp/cc) is a figure of merit that is used to indicate the 'state of tune' of an internal combustion engine. It is defined as the ratio of the engine's net power output to its displacement, the internal size. Power is measured at its rated speed and full throttle.
An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors. [1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or ...
Brake force, also known as brake power, is a measure of force applied by the brakes of a vehicle in order to decelerate it. It is one of the main components in determining a vehicle's stopping distance.
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
