250+ TOP MCQs on Sterling and Ideal Ericsson Cycle and Answers

Steam and Gas Turbines Multiple Choice Questions on “Sterling and Ideal Ericsson Cycle”.

1. Isoentropic processes in carnot cycle when replaced by constant volume process is called as _______
a) Dual cycle
b) Ericsson cycle
c) Stirling cycle
d) None of the mentioned

Answer: c
Clarification: Isoentropic process in carnot cycle when replaced by constant volume process is called as Stirling process.

2. Stirling cycle is reversible.
a) True
b) False

Answer: a
Clarification: Since isoentropic process in carnot cycle is replaced by constant volume process, Stirling cycle can be reversible.

3. Stirling cycle can also be called a closed regenerative cycle.
a) True
b) False

Answer: a
Clarification: Since Stirling cycle is reversible and is a closed cycle it can also be called as closed regenerative cycle.

4. Stirling cycle can also be categorized as ________
a) internal heat engine
b) external heat engine
c) internal combustion engine
d) none of the mentioned

Answer: b
Clarification: When work is supplied to Stirling engine, heating or cooling can be produced as per requirement, So Stirling cycle is categorized as an external heat engine.

5. Processes in Stirling cycle are _______________
a) Compression, Heat addition, Expansion, Heat removal
b) Compression, Heat addition, Expansion
c) Heat addition, Expansion, Heat removal

Answer: a
Clarification: Stirling cycle consists of four processes. They are
Compression
Heat addition
Expansion
Heat removal.

6. Compression process that takes place in Stirling engine is _________
a) Constant volume
b) Isothermal
c) Constant pressure
d) None of the mentioned

Answer: b
Clarification: In Stirling engine, Isothermal compression takes place.

7. In Stirling engine, pistons are arranged in __________
a) co-linear position
b) linear position
c) parallel position
d) none of the mentioned

Answer: a
Clarification: In Stirling engines, co-linear pistons are arranged.

8. In Ericsson cycle, heat addition is done by ___________
a) none of the mentioned
b) isochoric heat addition
c) isothermal heat addition
d) isobaric heat addition

Answer: d
Clarification: Heat addition is done by constant pressure process in Ericsson cycle.

9. Ericsson cycle is also known as external combustion engine.
a) True
b) False

Answer: a
Clarification: In Ericsson cycle, combustion is done externally and hence it is called an external combustion engine.
