# How Much Energy Does a Small Air Compressor Consume Daily?

## Question:

If a small air compressor operates on a 2.8 hp electric motor for 9.1 hours a day, how much energy is consumed by the motor daily?

## Answer:

The energy consumed by the electric motor is 6.88 x 10⁷ J.

In this scenario, the air compressor's electric motor operates at 2.8 hp for 9.1 hours each day. To calculate the energy consumed by the motor daily, we need to use the formula E = Pt, where E represents energy, P stands for power, and t is the time the motor operates.

Given that 1 hp is equivalent to 750 W, we first convert the power from horsepower to watts: 2.8 hp x 750 W = 2100 W

Next, we calculate the total energy consumed by multiplying the power by the time the motor operates: E = 2100 W x 9.1 hours x 3600 seconds = 6.88 x 10⁷ J

Therefore, the energy consumed by the electric motor daily is 6.88 x 10⁷ Joules. This calculation shows the amount of work the motor can do in a day.
