How much hp does bh give

BHP is pretty much the power of an engine in simple terms. The Brake Horse Power is the unit of power of an engine without any losses like heat and noise. The BHP determines the acceleration and top speed of a vehicle. Often fast and quick vehicles will focus more on the BHP than the torque.

BHP is defined as the power of an engine without any losses while HP or Horsepower is the power of a car with losses included. The crank HP is the value of power generated by an engine without transmission losses. Wheel HP is the power at the wheels which means it includes the losses of transferring power from the engine to the wheels.

The measure of a force which rotates about an axis is known as torque. In simple words, the force at which something rotates and as you know a lot of parts in a car have rotational motion.

From pushing of the piston to rotating the flywheel, all of this is done by the torque. Torque determines how much turning force a vehicle has. This, however, means slower cars. To keep it short and sweet, BHP affects the top speed and acceleration of a car while torque affects the amount of load you can carry without performance degradation. Take for example Kawasaki Ninja H2 which is built for speed. It has the power of BHP and Nm torque. If the force and distance are in the same direction, the angle is 0 degrees, which has a sine of one.

So to calculate work, just multiple the quantities. Torque is calculated using what is known as a cross product. The sine of zero degrees is zero, so torque would always be zero if a dot product would be used. Lots of people make the same mistake. Maybe this is why the imperial system has all but disappeared.

The metric system has no such distinction although in my opinion, it should. Most of that was good, but a dot product is calculated by multiplying the cosine of the angle between vectors by their magnitude, not sine.

Is that good or bad??? It does not contain any drivetrain losses. Or in other words net horsepower not gross horsepower. Whilst I applaud everyone for taking the trouble to contribute, the above exchanges are littered with techno-rubbish, and it is reasonably clear that none of the contributors have ever been directly involved in engine or vehicle performance measurements. I have, and rather than try to put everything straight here, I would recommend, to anyone interested, the Wikipedia article on Horsepower.

Some may find the more technical content a little daunting, but I strongly recommend reading all the way through as there are answers there for almost everyone. I confess I have not been through the Wikipedia article with a fine toothcomb, but on a speed-read it is dramatically more accurate than the stuff above. And Chris, that is NOT a maybe. Dear sir.. Difference between a diesel and a turbine. You must use a big heavy lossy gearbox to use a turbine in your tractor.

Its HP figure, taking into account that the power must go through the gearbox etc is HP; If you were to apply the breaks at its top speed, they would only need to stop the power of BHP, because that is all that is being transferred to the road. That means 14BHP has been lost during the process of transferring power to the ground, meaning a I take this answer to be more understandable for me.

The more you read the more the thread gets confusing, haha. Maybe that is one of the reasons the Bugatti cost so much. Example of car: Bhp can be measured at the engine output and hp can be measured at wheel out put.

HP is called as Indicated Horse Power i. IHP means the Horsepower actually deveploped at the engine shaft.

BHP means Brake horse power i. FHP means power wasted in Engine friction. This article confuses more than it explains. A much simpler and arguably more accurate explanation would be:.

One is a measure with everyday practicality. Neither measure the maximum rate of acceleration and are very different from torque, a measure that is thrown into this article for no good reason. Yes you can, you just get both the time it takes to do the job, and the energy needed, so if you have a timeframe, you can tell how much energy you need in cal. And is there a slope involved that I could factor size of engine or other notable variables? Bottom line question- what is the formula for the hp and bhp?

Horsepower was deemed equivalent to a horse moving 33, pounds of mass one foot in one minute. This new-found unit allowed Watt to show direct comparisons between his steam locomotives and the common horse that dominated the haulage business up until the invention of the steam engine.

Horsepower still survives as the main power unit for us petrolheads in the UK and you lot over in the USA, staving off any outside influences from Continental Europe and Australasia. Again, this power unit can be found by a torque translation using a similar equation to that of the Watt:. Horsepower can become a tricky business however, with values measured in different ways. BHP brake horsepower refers to the equipment needed to test the engines for their power outputs, with a large drum with a water brake within it measuring the braking force once the engine is spinning at a desired rate.

Over in the US, this is measured with only some ancillary components attached to the powertrain, missing things like the power steering pump which would lead to a lack of parasitic losses if in place. Only engineers tend to talk about indicated horsepower, and then just amongst themselves. However, it is worth noting, that depending on who you speak to, wheel horsepower and BHP are often used interchangeably — again adding to the confusion.
