Reliability and Failure Analysis Engineer Interview Questions and Answers

Brayton and Rankine cycles are thermodynamic cycles used in power plants and engines.

• Brayton cycle is used in gas turbine engines where air is compressed, heated, expanded through a turbine, and then exhausted.

• Rankine cycle is used in steam power plants where water is heated to produce steam, which expands through a turbine to generate electricity.

• Both cycles involve a series of processes to convert heat energy into mechanical work.

• Brayton cycle has a higher efficiency for ga...read more

Otto cycle is a theoretical thermodynamic cycle that describes the functioning of a typical spark ignition piston engine.

• Consists of four processes: isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection

• Used in spark ignition engines like gasoline engines

• Efficiency of the cycle depends on compression ratio

• Named after Nikolaus Otto, who invented the four-stroke internal combustion engine
