Heat engine efficiency formula

WebThe efficiency of an engine is defined as ratio of the useful work done to the heat provided. = = where, is the heat absorbed and is the work done. Please note that the term work done relates to the power delivered at the clutch or at the driveshaft.. This means the friction and other losses are subtracted from the work done by thermodynamic expansion. WebRead formulas, definitions, laws from Engines and Cycles here.
