Recap Chapter 4 and 5

In which type of cycle does the working fluid experience a phase change?

• Rankine cycle

• Brayton cycle

• Both Rankine and Brayton cycles

• Neither Rankine nor Brayton cycles

Which cycle is commonly used in steam power plants?

• Rankine cycle

• Brayton cycle

• Carnot cycle

• Otto cycle

Which process in the Rankine cycle involves heating the working fluid at constant pressure?

• Isentropic compression

• Isentropic expansion

• Constant pressure heat addition

• Constant pressure heat rejection

In the Brayton cycle, which component is responsible for extracting work from the high-pressure working fluid?

• Compressor

• Turbine

• Heat exchanger

• Condenser

Which type of cycle is commonly used in gas turbine engines?

• Rankine cycle

• Brayton cycle

• Carnot cycle

• Diesel cycle

In the Rankine cycle, what is the purpose of the condenser?

• To increase the pressure of the working fluid

• To remove moisture from the working fluid

• To increase the temperature of the working fluid

• To decrease the temperature of the working fluid

Which process in the Brayton cycle involves heating the working fluid at constant pressure?

• Isentropic compression

• Isentropic expansion

• Constant pressure heat addition

• Constant pressure heat rejection

What is the major difference between the Rankine and Brayton cycles?

• Rankine cycle uses a gas as the working fluid, while Brayton cycle uses a liquid.

• Rankine cycle operates on a closed loop, while Brayton cycle is an open system.

• Rankine cycle involves a phase change, while Brayton cycle does not.

• Rankine cycle is more efficient than the Brayton cycle.

Which component is responsible for converting the thermal energy of the working fluid into mechanical work in the Rankine cycle?

• Condenser

• Turbine

• Compressor

• Heat exchanger

In the Rankine cycle, what is the purpose of the pump?

• To increase the pressure of the working fluid

• To decrease the pressure of the working fluid

• To increase the temperature of the working fluid

• To decrease the temperature of the working fluid
