15. Amongst which of the following is true about the reciprocating engine?

1. Reciprocating engines have the same power-to-weight ratio as gas turbine engines
2. Reciprocating engines have a higher power-to-weight ratio than gas turbine engines
3. Reciprocating engines have a lower power-to-weight ratio than gas turbine engines
4. None of the above

Answer: C) Reciprocating engines have a lower power-to-weight ratio than gas turbine engines.

Explanation:

Reciprocating engines are commonly called piston engines. When compared with gas turbines, reciprocating engines have a lower power-to-weight ratio; they are heavier or give power output.
