What do you mean by horsepower?

What do you mean by horsepower?

Horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minutethat is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

What is the calculation for horsepower?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

How BHP is calculated for an engine?

BHP = Q × P / (1714 × n) *Many positive displacement pumps are assumed to operate at 90% efficiency. A value of 0.9 is often used for this calculation. For more accuracy, refer to your pump manufacturer’s pump test sheets.

Is a higher BHP better?

In a car, hp describes the total amount of power an engine can produce. In this way, the higher the hp the more power the car has and so the faster the top speed.

Which is better cc or BHP?

CC merely determines how much volume of air-fuel mix the engine can burn whereas BHP is a measure of how much mechanical energy the engine can extract by burning the air-fuel mix. So in general larger the CC larger the BHP by virtue of the fact that more CC = more fuel burnt and hence more energy extracted.

How does CC compare to HP?

The “cc” rating—200cc, 350cc and so on—is just a measurement of the engine displacement, or the amount of volume moved by the pistons in a single revolution of the engine. In contrast, “horsepower” measures the work an engine can do. One horsepower is officially equivalent to 746 watts of power.

What is CC power?

Without getting too technical, the size of an engine refers to the total volume of air and fuel being pushed through the engine by the cylinders. It’s measured in cubic centimetres (cc). For example, a 1,000cc engine can displace one litre (1,000 cubic centimetres) of this air-fuel mixture.

What is a good BHP for a car?

Typical figures A fairly typical small family car engine puts out, say, 60bhp (brake horse power) at 5000rpm. The same engine can be tuned or modified so that it gives 80bhp at 6000rpm. But although the power is greater, the peak torque can actually be less, as well as occurring at a higher engine speed.
