Determine the monthly electricity consumption in the electric motors of eight oil rigs, if the voltage

Determine the monthly electricity consumption in the electric motors of eight oil rigs, if the voltage on them is 220 V, and the current strength is 3 V.

Data: U (voltage on oil rig motors) = 220 V; I (current) = 3 A; N (number of oil rigs) = 8 rigs.

Reference data: we accept n (number of days in a month) = 30 days; t (duration of a day) = 24 hours.

1) Determine the power of one electric motor: P = U * I = 220 * 3 = 660 W.

2) Electricity consumption by the engine of one oil rig: W1 = P * n * t = 660 * 30 * 24 = 475200 W * h.

3) Electricity consumption for eight towers: W = N * W1 = 8 * 475200 = 3801600 W * h ≈ 3.8 MW * h.
