WebIn thermodynamics, the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, … WebThe total mass flow rate of the fuel and the effective engine output power yield an “overall” SFC. As discussed in Section 2.4.3, effective SFC is always larger than indicated SFC. Similarly, overall SFC is the largest SFC value due to the additional fuel mass flow rate now associated with the same effective output power.
