AC/DC MACHINERY question,please help me?

A 20kw,200V shunt generator is operated at rated load. if the driving engine is developing 30bhp (break horse power), determine the iron and friction losses.Answer is IFL=1039W.Thanks a lot.

Answer:

746 watts = 1 hp 30 brake hp are going into the sysystem so 30*746 watts is going into the generator = 22,350 watts if 20,000 watts is leaving the system as electrical power, that only leaves 350 watts available for losses.
