Energy Consumption Calculation of a Small Air Compressor

How much energy is consumed by the motor daily?

A small air compressor operates on a 2.8 hp (horsepower) electric motor for 8 hours a day. 1 hp equals about 750 watts.

Answer:

The energy consumed by the motor is 1008000 J.

Energy is the ability of the capacity to perform work. In this case, the energy consumed by the electric motor daily can be calculated using the formula:

E = Pt (Equation 1)

Where:

• E = Energy consumed by the electric motor daily
• P = Power of the air compressor = 2.8 hp = (2.8×750) = 2100 J
• t = Time = 8 hours = 8×60 = 480 seconds

Substitute these values into Equation 1:

E = 2100×480

E = 1008000 J

Therefore, the energy consumed by the motor daily is 1008000 joules.

Energy is a crucial concept in physics and engineering, and understanding energy consumption is essential for efficient operation of electrical devices and machinery. To learn more about energy and its various forms, you can explore additional resources on the topic.
