What work does a 40 W fan motor do in 1 minute?
September 29, 2021
The fan motor power can be calculated using the formula:
N = A / t, where N is the power of the fan motor (N = 40 W), A is the useful work done by the fan (J), t is the operating time of the fan motor (t = 1 min = 60 s).
Let us express and calculate the useful work of the fan motor:
A = N * t = 40 * 60 = 2400 J = 2.4 * 10 ^ 3 J = 2.4 kJ.
Answer: The perfect work of the fan motor is 2.4 kJ
