What work does the fan do in 10 minutes if its power is 30 W?
| June 15, 2021 | education
The fan power can be calculated using the formula:
N = A / t, where N is the fan power (N = 30 W), A is the mechanical work performed by the fan (J), t is the fan operation time (t = 10 min = 600 s).
Let us express from the formula and calculate the mechanical work of the fan:
A = N * t = 30 * 600 = 18000 J = 18 kJ.
Answer: The mechanical work performed by the fan is 18 kJ.
