How much energy does a small air compressor consume daily?
How much energy is consumed by the motor daily?
Calculate the energy consumed by a small air compressor that operates on a 2.3 hp electric motor for 8.2 hours a day. 1 hp equals about 750 watts. Answer in units of J.
How much does it cost per day to operate the compressor?
If electricity costs 21 cents per kilowatt-hour, how much does it cost to run the compressor each day? Answer in units of cents.
Energy Consumption Calculation:
To calculate the energy consumed by the motor daily, we need to convert the horsepower to watts and then multiply it by the operating hours.
Given: 2.3 hp * 750 watts = 1725 watts
Energy consumed daily = 1725 watts * 8.2 hours = 14,145 J
Operating Cost Calculation:
To calculate the operating cost of the compressor per day, we need to convert the energy consumption from J to kWh and then multiply it by the electricity cost.
Energy consumed per day = 14,145 J = 0.00393 kWh
Operating cost per day = 0.00393 kWh * $0.21 = $0.8277
The small air compressor consumes approximately 14,145 J of energy daily when operated by a 2.3 hp electric motor for 8.2 hours. This energy consumption can be calculated by converting the horsepower to watts and then multiplying it by the operating hours.
Similarly, the operating cost of running the compressor each day is approximately $0.8277 when electricity costs 21 cents per kilowatt-hour. This cost can be calculated by converting the energy consumption from J to kWh and then multiplying it by the electricity cost.
