How is Specific Power Calculated? The Specific Power of a compressor is the energy used divided by the compressed air output. Using this calculation, we can see that HPC's SM13 Rotary Screw Compressor, Specific Power is 6.4 KW/m3/min. Energy Used ÷ Compressed Air Output = Specific Power. 8.56kW ÷ 1.33m³/min = 6.4 KW/m3/min

Specific power or power-to-weight ratio is a measure of performance for an engine in a vehicle or in a power plant. It is defined as the power output by it divided by its mass, typically in units of W/kg or hp/lb. This value allows for a clear metric of the power that is independent of the vehicle or power plant's size: . Turbines, like a gas turbine in a plane, typically have the largest ...
Let's consider a chiller with a cooling capacity of 20 tons and a COP of 4. The power consumption can be calculated as follows: Power Consumption (kW) = (20 Tons * 3.517) / 4 = 17.585 kW. This indicates that our chiller consumes 17.585 kilowatts of power to provide the cooling capacity of 20 tons with a COP of 4.
