Mechanical efficiency of a gas turbine as compared to internal combustion Reciprocating engine is: A higher B lower C same D unpredictable

I believe the answer is  A 

Fresh atmospheric air flows through a compressor that brings it to higher pressure.

A reciprocating engine, also often known as a piston engine, is a heat engine (usually, although there are also pneumatic and hydraulicreciprocating engines) that uses one or more reciprocating pistons to convert pressure into a rotating motion.

A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressorcoupled to a downstream turbine, and a combustion chamber in-between.

The basic operation of the gas turbine is similar to that of the steam power plant except that air is used instead of water. Fresh atmospheric air flows through a compressor that brings it to higher pressure.

C

Option C

I suggest A

  A higher  

D Unpredictable
