How to Use the Calculator
- Enter the flow rate of the gas in cubic meters per hour (m³/h).
- Enter the inlet pressure of the gas in bar.
- Enter the outlet pressure of the gas in bar.
- Enter the isentropic efficiency of the compressor as a percentage (default is 75%).
- Click the "Calculate" button to compute the energy consumption.
- The results will show the pressure ratio and the energy consumption in kilowatt-hours (kWh).
Working Principle
The calculator uses the following formula to estimate energy consumption:
Energy Consumption (kWh) = (Flow Rate × Pressure Ratio ^ 0.28) / Efficiency
Where:
- Flow Rate is the volume of gas compressed per hour.
- Pressure Ratio is the ratio of outlet pressure to inlet pressure.
- Efficiency is the isentropic efficiency of the compressor, representing how efficiently the compressor converts electrical energy to mechanical energy.
Applications
This calculator can be used by engineers, technicians, and facility managers to:
- Estimate the energy requirements of compressors.
- Compare the efficiency of different compressors.
- Optimize compressor operations to reduce energy consumption.
- Conduct energy audits for industrial facilities.
