1. Determine the mechanical efficiency of a Stirling cycle engine operating with a 1300.°F heater and a 100.°F cooler. The engine produces a net 10.0 hp output with a heat input of 80.0 × 103 Btu/h.
2. In 1964, an experimental Stirling engine was installed in a modified Chevrolet Corvair at the General Motors Research Laboratory. Alumina (aluminum oxide) heated to 1200.°F served as the heat source for the engine, while the atmosphere at 100.°F served as the heat sink (because of the use of alumina in the engine, the car was dubbed the Calvair by GM researchers). Assuming a mechanical efficiency of 67.0%, determine the actual thermal efficiency of the engine based on a cold ASC analysis.
