Generator's output

ENRG

Hi everybody:

Help me out with this if you don't mind.

A 2000 ft lb per second source rotates a generator shaft at 60 RPM; It is generally agreed (not by everyone) that this produces 17.038 KW of power.

What is not clear is if this is 17.038 KW per SECOND then the total HOURLY power would be calculated : 17.038KW *60* 60= 61336.8 KWH.

Some say that the total production of this generator is 17.038 KWH (IN ONE HOUR)

What say you?

kWH = kW * H

EDIT -- removed the confusion which then followed....

Yikes - you have to know what a kW and a kWh are. Check the units: Since the "h" is hours, kW * h = kWh

kW is kilojoules per second, but don't let that confuse you - if you want kWh, you just need the kW and the number of hours.

Yikes is right. :tongue2: Thanks for catching my error Russ. I'll edit my post to remove the confusion.
