What is BHP (break horse power)? I know the more it is the faster your car is but what exactly does...?

Break horsepower is a measure of the power (energy over time) that your engine can apply through the wheels of the car. It determines the *torque* (twisting power) that the wheels can then apply against the road.The horsepower that an engine produces determines two things that are noticeable to the driver:- The maximum rate of acceleration of the car- The top speed of the car.The reasons for the first are obvious. The reason for the second is, that as your car goes faster, the external forces that make your car slow down increase (wind, friction etc) therefore you need greater power to make the car go faster.There are several definitions of horsepower (it's not a metric or SI unit), but when talking about cars, the definition usually meant is 0.7457 kW (33,000 ft·lbs per minute).

Defenition Steam Boiler?

A steam boiler designed to suit the marine environment and generally arranged to supply steam to the main propulsion machinery, ship's service electric generators, feed-pump drivers, and other auxiliary services.Marine boilers are usually of the two-drum water-tube type with water-cooled furnaces, superheaters, desuperheaters, and heat recovery equipment of the economizer or air-heater type. The majority of ships are fitted with two boilers, although some large passenger ships may have three or more. Some cargo ships are fitted with only one boiler, and in some of these cases a smaller auxiliary boiler may be fitted for emergency or in-port steaming use.Marine boilers are generally arranged for oil firing. Oil is used extensively because of its simplicity of handling and storing and the fact that it can be stored in spaces that often cannot be used for carrying cargo. See also Boiler; Marine machinery; Steam-generating unit.
