Energy Consumption Calculation of a 10 HP Motor

How can we calculate the energy consumed by a 10 HP motor in a year?

A 10 HP motor runs for 2.5 hours a day. What would be the energy consumed by the motor in a year?

Answer:

The total energy consumed in a year would be approximately 24,500,700,000 joules.

To calculate the energy consumed by a 10 HP motor running for 2.5 hours a day for a year, we first need to convert horsepower to watts. As given, 1 Horsepower equals 746 watts. Therefore, the power of this motor is 10 HP * 746 Watts/HP = 7460 Watts. Next, we convert the time from hours to seconds because energy consumed is typically measured in joules (1 watt = 1 joule/second). So, the motor runs for 2.5 hours * 60 minutes/hour * 60 seconds/minute = 9000 seconds per day. In a year, this would be 9000 seconds/day * 365 days/year = 3,285,000 seconds. Therefore, the energy consumed by the motor in a year is power * time = 7460 Watts * 3,285,000 seconds = 24,500,700,000 joules.
