Specific power - Energy Education

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 ...

How To Calculate Compressed Air Savings - Design World

Jan 12, 2013· Specific power at 30% load would be 21.8 kW/100 cfm from Figure 5. kWh = (cfm x specific power x hours)/100 = (148 x 21.8 x 3000)/100 = 96,790 kWh. For the 200 cfm load: Specific power of the VSD at 41% load (200/488) from Figure 5 = 20.2 kW/100 cfm. kWh = (cfm x specific power x hours)/100 = (200 x 20.2 x 2500)/100 = 101,000 kWh

What is Specific Fuel Consumption? (with pictures)

May 17, 2020· Specific fuel consumption, abbreviated SFC, compares the ratio of the fuel used by an engine to a certain force such as the amount of power the engine produces. It allows engines of all different sizes to be compared to see which is the most fuel efficient.
