Chapter 3, Problem 3A.2ST
Interpretation Introduction
Interpretation:
The increased temperature of the hot source has to be calculated to increase the efficiency of heat engine by
Concept Information:
Heat engine: combustion of fuel producing heat that is transferred and completely converted into work with maximum efficient. All heat engines have both ‘hot’ regions, the source and ‘cold’ region, the sink. Some energy is dispersed into the cold sink as heat and not used to do work.
Efficiency of heat engine:
