Unistal Systems Interview Questions and Answers

Carnot cycle is a theoretical thermodynamic cycle that operates between two heat reservoirs.

• It consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression.

• It is used to determine the maximum efficiency that a heat engine can achieve.

• The efficiency of the Carnot cycle depends only on the temperatures of the two reservoirs.

• It is named after French ph...read more

Petrol engines use spark ignition while diesel engines use compression ignition.

• Petrol engines have higher RPM and power output compared to diesel engines.

• Diesel engines have higher torque and fuel efficiency compared to petrol engines.

• Petrol engines are lighter and quieter compared to diesel engines.

• Examples of petrol engines include those used in cars, motorcycles, and small aircraft, while diesel engines are commonl

Adiabatic process is a thermodynamic process where no heat is exchanged with the surroundings.

• Adiabatic process occurs when a system is thermally insulated from its surroundings.

• In this process, the internal energy of the system changes due to work done on or by the system.

• Examples of adiabatic processes include the compression or expansion of a gas in a piston-cylinder system.

• Adiabatic cooling occurs when air rises in...read more
