For a jet propulsion unit , ideally the compressor work and turbine work are: A equal B unequal C not related to each other D unpredictable

These typically consist of an engine with a rotary (rotating) air compressor powered by a turbine with the leftover power providing thrust via a propelling nozzle.

Gas turbines are rotary engines that extract energy from a flow of combustion gas. They have an upstream compressor coupled to a downstream turbine with a combustion chamber in-between. In aircraft engines, those three core components are often called the "gas generator. There are many different variations of gas turbines, but they all use a gas generator system of some type.
