How much does it cost to run a small air compressor each day?
What is kilowatt-hour?
A kilowatt-hour is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ).
How do we calculate the amount it takes to run the compressor daily?
To calculate the amount it takes to run the compressor daily, we use the formula below:
Formula: A = PtC/1000 ............ Equation 1
Calculation:
Given: Power of the compressor (P) = 2.9 hp = 2.9 x 746 = 2163.4 W
Time taken (t) = 4.9 hours
Electricity cost (C) = 22 cents per kilowatt-hour
Substitute these values into Equation 1:
A = 2163.4 x 4.9 x 22 / 1000
A = 233.21 cents
Answer:
It costs 233.21 cents to run the small air compressor each day.
The small air compressor operates on a 2.9 hp electric motor for 4.9 hours a day. With an electricity cost of 22 cents per kilowatt-hour, the calculation shows that it costs 233.21 cents to run the compressor daily.
A kilowatt-hour is a standard unit of energy measurement, representing one kilowatt of power used for one hour. This allows for easier calculation of energy usage and cost.
By using the formula A = PtC/1000, where A is the amount, P is the power of the compressor, t is the time, and C is the electricity cost, we can determine the cost of running the small air compressor each day accurately.
Understanding the concept of kilowatt-hour and the calculation involved helps in managing energy consumption efficiently. It is essential to consider these factors to effectively control operational costs.
