Answer:

0.47 kW

Explanation:

[tex]P_{out} = 18.65kW[/tex]

The friction and windage losses is given to be 2.5% of [tex]P_{out}[/tex]

Therefore, the friction and windage losses [tex]P_{fw} = \frac{2.5}{100} * 18.65 kW[/tex]

                                      [tex]P_{fw}[/tex] = 0.025 × 18.65 kW

                                      [tex]P_{fw}[/tex] = 0.46625 kW

                                      [tex]P_{fw}[/tex] = 0.47 kW

The friction and windage loss of the induction motor is 0.47 kW
