I am working on an accelerationdyno right now but I am not sure about the calculation of HP and Nm. The calculations I am using goes like this:
Acceleration= ((The difference between 2 measurements of RPM/time between the measurements) * pi^2)/60
Nm= acceleration*the calculated moment of inertia on the rollers
Watt= RPM*Nm/5252
HP= Watt * 1,36
I think don't think I am getting the right values, they seem to be too low. Have I done something wrong in the calculations?
