Question

Find the efficiency of a motor which receives 4 KW and delivers 4 H.P.

Answer 1

Answer:

0.746

Step-by-step explanation:

Efficiency of a motor can be calculated as Efficiency = $\frac{Power-delivered}{Power -received}$

H.P is a common term used in engineering, which refers to 'Horse Power'.

1 H.P = 746 Watt (approximately)

Therefore, efficiency = (4 x 746)/(4 x 1000) = 0.746

P.S Efficiency of any machine is always less or equal to one.

Hope this helps!
