Probably, it's simple: stop using integers!
When you divide you integer values, you get an integer result - that then gets cast to a decimal value to multiply by the RPM. Since 14 is less than 100, 14/100 is 0 as an integer, so you always get zero as a result of the whole calculation.
Try adding an M suffix to all your constants to force them to be decimal values.

If that doesn't fix it, you need to tell us exactly what you expect, and what you are getting.
