    Frequently Asked Questions - centrifugal compressor power Conversion FAQs:

    How to calculate centrifugal compressor power?

    The formula to determine centrifugal compressor power appears as P = (ṁ × Cp × ΔT) / η, with power expressed in W, mass flow rate in kg/s, specific heat at constant pressure in kJ/kg·K, temperature rise in K, and efficiency in η. This formula functions for polytropic or isentropic compression operations based on your recorded data. The use of polytropic formulas requires including the pressure ratio along with the gas constant to achieve better accuracy in results.

    How to calculate compressor kW from pressure and flow?

    The calculation for compressor kilowatts involves P (kW) = (k / (k - 1)) × (P1 × V × [(P2 / P1)^((k - 1)/k) - 1]) / (η × 1000). This formula calculates shaft power in kilowatts (kW) through (k / (k - 1)) × (P1 × V × [(P2 / P1)^((k - 1)/k) - 1]) / (η × 1000). The variables include P1 and P2 for inlet and outlet pressures (Pa), V represents volumetric flow rate (m³/s), k stands for specific heat ratio, and η denotes efficiency. The calculation results in kilowatt shaft power.

    How to calculate compressor power in watts?

    Watt's calculation requires multiplying Work Done by Mass Flow Rate and multiplying the result by Efficiency if necessary. The evaluation of work employs thermodynamic relationships, which state that W = Cp × ΔT. The calculation requires flow rate multiplication, while efficiency division is needed when needed. The units must always correspond (J/s = W), and you can transform kW to W by multiplying it by 1,000.

    How much kW is needed for a centrifugal compressor?

    Kilowatts for a system depend on both gas composition and flow volume, and pressure ratio, as well as operating efficiency. A typical rule: Power (kW) = Flow rate (kg/s) × Cp × Temp rise (K) / Efficiency. Standard mathematics or software tools apply for computing the required kW of power when using air at 1.4 specific heat ratio. A rise in pressure ratio values along with flow rate requires higher power generation.

    How to convert compressor horsepower (HP) to kW or watt?

    The conversion from HP values requires multiplication by 0.7457. For watts, multiply by 745.7. For example, a 10 HP compressor = 7.457 kW or 7457 watts. Power ratings become easier to verify through this calculation method.
