HP to Kw - HELP

calculus...

conversions, loadings, reduction factors..

navigations, dive times, rate changes, mixture compensations.

factoring distance to go vs fuel available and consumption rate to determin the optimal burn rate to get to the destination at the quickest speed without having to stop for fuel OR what speeds to do what legs to make what servos.

if your serious about what you landrover can get you to then its a nice to have.

Thank everyone for your input but....

ENOUGH!!!!:p

So the Merc Jeremy drove with 550hp has 412 kw....... makes the V8 supercars look pretty ordinary...at least the road versions:twisted:

Calculus is a waste of time at school - teach it in Uni.

Calculus was Useless at Uni too:(

Or just refer to the in-car computer for range to empty in a D3.

It's used to give these sort of results:
Area under a curve.
Length of a curve.
Slope of a line.
Point of inflexion (where a line straightens out between two curves).
Radius of curvature.
Volume enclosed.
Volume excluded.
Predicting stress, strain or deflection at a particular point.
Predicting the amount of damping you need to stabilise something.
Predicting the behaviour of oscillating systems.

You may ask, "why not just measure these things"?
The answer is, because building a machine, device or full size model just to test or measure something like this is very expensive and time consuming. If you can do the maths correctly then you've got not only a good prediction, but also a good idea of how accurate that prediction can be.

That's how we engineers earn our keep.:)

Cheers!

100kw = 135 horsepower. Divide kw by 3 and multiply by 4. That example is an MV Agusta Evo.

I loved calculus at school - but I still think it's a Uni subject. We had to study a bit more of it at Tech when I was doing my electronics course.

Now I remember practically nowt of it!

Dunno. We weren't taught it until Year 11.

Hewlett Packard / Kenworth ?

Must use calculus to work that one......
