horsepower vs. PS?

Post by **POS_S13** » Tue Dec 23, 2003 12:12 pm

what is ps? lotsa japanese parts websites use the term ps? is it the same as horsepower?

Post by **Blackbird S14** » Tue Dec 23, 2003 12:12 pm

1 horsepower is = to . 98630 PS

Pferdstärke

You had everything plural :pface

Actually plural is correct.One reason why germans that are speaking english often say horsepowers instead of horsepower.

So PS is the literal German for horsepower except in plural.Often you say DIN PS which stands for "Deutsches Institut for Normung", the german equivalent to our former NBS (National Bureau of standards).

The reason PS is kinda widespread in many countries, is cuz that DIN was one of the first organizations of its kind, providing norms, and many emerging industrial countries in the late 19th + early 20th century, found it simpler to follow the DIN norms while they were building their own similiar institutions.

ok but how is it calculated?

i know that

hp= torque X rpm / 5280 (1 mile?)

so whats the formula for PS?

Post by **Exar-Kun** » Tue Dec 23, 2003 12:12 pm

multiply that answer times .98630:p-chet

It is kinda like my boost gague in Mega Pascals (MPa). For the longest time I had no clue how to convert the readings to somethign I can understand.

PS is now defined as a certain number of kw (kilowatt).

I <think> its something like .74 kw or thereabouts. (I am sure someone will look it up and post a more accurate # soon)

i guess no-one caught the slip up...

its 5252, not 5280

Wirklich? ... Ich finde dieses sehr verwirrendeich und ein Freund aus Deutschland, das für eine Weile über dem argumentiert wurde, er behaupteten, daß es eins war, nicht plural.

Schade, das ist was ich an das Hören auf jene nervtötenden Inhaber 200SX gelange :rolleyes

Fred, was tun Sie für Weihnachten und neue Jahre? Sind Sie Silvester feiernd?

the horsepower calculation isnt related to the feet in a mile, its how long it takes to lift a load [forgot the exact] one foot in one minute.

yeah, it's how long it takes a horse to pull 100 pounds in one minute

or something like that

Alan your german friend was wrong..

.This german friend remembers his hischool physics well enough.It's plural.

300 PferdeStaerken (written as 300 PS, or 300 DIN PS). singular form would be spelled different; 1 PferdeStaerke (=1 PS).

Fred...

Post by **lessthanjakejohn** » Tue Dec 23, 2003 12:12 pm

one HP is the same as .75 KW, so thats about right

It's also how I remember it but he SWORE to me it was the other way around ... oh well now we all know better heheh.

oh man, i butchered my own statement. "how LONG it takes to lift a load one foot in one minute"

look at it closely, and then make fun of me...

its the energy required to lift 550 pounds one foot in one second.

or 33000 pounds one foot in one minute.

Post by **lessthanjakejohn** » Tue Dec 23, 2003 12:12 pm

torque = a unit to represent a certain type of work. Work = force x distance, With torque, ft-lbs, foot *lbshorsepower = a unit to represent the amount of work done in a certain time (work / time)

For example with torque: I can twist a rod to lift 500 pounds 500 feet.

For hp: I can lift that 500 lbs, 500 feet in 50 seconds.

I wish we went the way of the metric system as it is much easier to convert and understand:

Unit of Work = Newton * Meter or commonly called a jouleUnit of power = Joule / Second or commonly called a watt

To get PS you must have to take batterbongs * fleptometers and then take the result of that and divide it my mecodiveins

Post by **IvoryJ30t** » Tue Dec 23, 2003 12:12 pm

and the product of that is the multiplicative inverse of the meaning of life.

Taken from the best book ever, Machinery's Handbook, twenty-sixth edition.

Post by **Rex** » Tue Dec 23, 2003 12:12 pm

Found this, did not know it

One of the many formulae for calculating WATTS is…

WATTS = TORQUE x RADIANS/SEC

The formula for RADIANS/SEC is…

RADIANS/SEC = (RPM / 60) x 2Pi

Plugging in the TORQUE # and RPM said TORQUE is reached and we get (sample below)

RADIANS/SEC = (5,000 / 60) x 6.28 (approximate) = 83.3 * 6.28 = 523.124

Plugging THAT number in we get…

WATTS = 300 x 523.124 = 156,937.2

KWATTS = WATTS/1000 = 156,937.2 / 1000 = 156.937KW.

This assumes a wheel diameter of 2 feet (1 foot radius) and an RPM of 5,000 to “calculate” torque and radians/sec, respectively.

That gave me a headache, and didn't address the PS question at all:(

hp vs. ps is quite simple actually. the horses in the U.S. are slightly stronger than those in germany so when the averages are taken it comes out to .9863 of our horse's work is equal to the work of 1 german horse's work

horsepower vs. PS?
