You have to convert RPM to radians per sec, 2*pi*RPM/60

Putting it all together

HP = (2*pi)*T*RPM/(60*550) = T*RPM/5252.113

Re: How to convert Revolution per Minute(RPM)

I tried that formula in the program QBasic and it didn't work.
How would you do this?
This is a question that might help some users.
I couldn't find anything so far in my search.....

Re: How to convert Revolution per Minute(RPM)

John's answer is correct. The short version of the formula is:

Horsepower = Torque * RPM / 5252.113

where Torque is in Ft-Lb and RPM is in revolutions per minute. The formula should work just fine in QBasic.

Measure the torque and rpm at the prop shaft and use the formula above.
