Brake Horse power to newton meter torque
How do I convert 480 Brake Horse Power to newton meter torque?

#2




Re: Brake Horse power to newton meter torque
Horsepower to Torque is not a direct conversion. You would also need to know the RPM. As the conversion would differ for each RPM.
Here is some additional information, in addition to the formulas you need. http://www.carvideos.net/articles/h...wer_torque.asp

Re: Brake Horse power to newton meter torque
how do you work out brake horse power??

Re: Brake Horse power to newton meter torque
You have to know the torque and the rotational speed.
In English units, you need torque in footpounds, and rotational speed in radians per second. Multiply the two to get power in foot poundsforce per second; 1 HP = 550 ftlbf/s In metric units, the product of torque in newtonmeters, and rotational speed in radians per second is power in watts. 1 HP = 746 W (rounded) Note: If you have rotational speed in RPM, multiply by 2*pi and divide by 60 to get radians per second.

Re: Brake Horse power to newton meter torque
HP= Torque in Newton meters x RPM
__________________________ 5252 You must know RPM or max. and min rpm of the rotor or wheel and you will have max and min HP

Your constant of 5252 is wrong. It results from 1 HP = 33000 ft·lbf/min, and converting revolutions to radians (2*pi). Dividng yields about 5252, but only works for torque in ft·lbf. For metric, multiply RPM by 2*pi/60 to get radians per second, that times newton·meters of torque gives watts; divide by 745.7 W/hp to get horsepower. That net result of all that is replace 5252 by 7120.9 (or 7121). Of course in metric, the proper thing to do is stop with watts or kilowatts. Horsepower is for farmers.

Re: Brake Horse power to newton meter torque
how do i convert 110 newton meters to brake horse power

Re: Brake Horse power to newton meter torque
You also need RPM. See post #4 or #6 for details.

Re: Brake Horse power to newton meter torque
[QUOTE=JohnS;72849]I agree both torque and rpm are needed.
