hi mate)Question fun adn serios

[schumiGO]

Yesterday i saw torque and power plot VS RPM of some car...

And i remember that P=RPM*Torgue if we have smth that can rotate and has torque....



accordin formula Power line on plot must be torque line * by lineral-increasing RPM graf))))

Question is))) WHy it in't so???

Why i didn't see such correlation??
Why is Power and torgue lines is nearly independent??

ShumiGO,

Horsepower= (torque (ft-lbs) x rpm) / 5252.

More specifically, a horsepower is 33,000 ft-lbs/min, 2545 Btu/hr or 746 Watts. Take your pick. Thus, horsepower will increase linearly with speed, at a constant torque or BMEP level.

Sounds easy enough on paper, right? Increase your engine speed and your horsepower will increase a like amount. If only it were so!!!!
