| Parameter | Description | Value | Units | Source/Calculation |
|---|---|---|---|---|
| Electricity Cost | Cost per kilowatt-hour | $0.12 | USD/kWh | Local utility bill |
| Compressor Efficiency | Efficiency of the air compressor (as a percentage) | 80% | % | Manufacturer’s data |
| Compressor Power | Rated power of the air compressor | 10 | kW | Manufacturer’s data |
| Operating Hours | Number of hours the compressor operates per day | 8 | hours/day | Estimate or log data |
| Days in Operation | Number of days the compressor operates per year | 250 | days/year | Estimate or log data |
| Air Demand | Average compressed air demand | 100 | cfm | Measurement or estimate |
| Pressure | Operating pressure of the compressed air system | 100 | psi | Measurement or estimate |
Now, let’s calculate the compressed air cost per year:
- Electricity Consumption per Hour = (Compressor Power) / (Compressor Efficiency)
- Electricity Consumption per Hour = 10 kW / 0.80 = 12.5 kW
- Electricity Consumption per Day = (Electricity Consumption per Hour) x (Operating Hours)
- Electricity Consumption per Day = 12.5 kW x 8 hours = 100 kWh/day
- Electricity Consumption per Year = (Electricity Consumption per Day) x (Days in Operation)
- Electricity Consumption per Year = 100 kWh/day x 250 days/year = 25,000 kWh/year
- Annual Electricity Cost = (Electricity Consumption per Year) x (Electricity Cost per kWh)
- Annual Electricity Cost = 25,000 kWh/year x $0.12 USD/kWh = $3,000 USD/year
- Cost per Cubic Foot of Compressed Air = (Annual Electricity Cost) / [(Air Demand) x (Pressure) x (Days in Operation)]
- Cost per Cubic Foot of Compressed Air = $3,000 USD/year / [(100 cfm) x (100 psi) x (250 days/year)] = $0.12 USD/cubic foot
This table and calculations provide you with an estimate of the annual compressed air cost based on the given parameters. You can adjust the values in the table to reflect the specific characteristics of your compressed air system for a more accurate cost estimation.
