An "open cycle" of a gas turbine is best described by which of the following statements?

Correct Answer: Option D — Working fluids are taken in, transformed, and then discarded.

An open cycle gas turbine continuously draws in ambient air, compresses it, adds fuel for combustion, and exhausts the resulting gases into the atmosphere. Unlike closed-cycle systems that recirculate the working fluid, the open cycle discards the working fluid after a single pass through the engine components.
