yes so if i find that over 1second there is an increase of 250rpm, ex from 4000 to 4250; can i determine the engines/sources hp?

i looked quickly on wiki for the formula for hp. I am not sure how the constant 5252 was found. If you could lead me in the righ direction that would great.

as the title states I am looking to solve how to calculate power (horsepower) by measuring the change in rpm over a few seconds. torque will be kept constant at 200lbs/ft. hp= (torque x rpm) / 5252 since torque will be held constant it reduces to: hp= C x rpm where C is 200/5252 so...
