Solution:

Approach:

As listed in equations for derived units in the Uses, hp refers to horsepower, Then the Conversions for power.

1hp1=0.7457kw.1hp=550(ft1 b)s

Solution:

Here kijo prefix in, 1000=103

Applying the Conversion factor to the engine's power rating, we have.

P=(10hR)(0.7457kwAR)=7.457(hR)(kwhp)=7.457kw

Discussion:-

In terms of the derived unit watt, the motor produces cm output of 7457w.

However, since this numerical value is greater then 1000, the prefix "kiJo" is used,

P=7.457kw
