Energy Usage Calulcation

I have no idea what this nameplate efficiency or the throttle fan is about.... however,
Efficiency is power (kW) out / power (kW) in - you can convert hp into kW quite easily.
But you need to be able to measure both the input and the output powers.

Here looks like a reason why asking me to find the answer causes issues. All I know is he's putting some slides together and asked me to ask a mate of mine who's an electrical engineer. Sadly he's proving to be elusive so I'm here!
As such I assume answer needs to be theory based only rather than real work potential improvements.

Cant be theory if you are asking "how to measure" though.
If you want the efficiency of motor, you need to know the electrical energy going in (joulemeter) and then a way to measure the useful energy out (kinetic). But then I always tend to work from first principles so maybe someone else has a more derived solution!
