What is the carrier in steam turbine?

In a steam turbine, the carrier refers to the steam that acts as the working fluid. The steam, produced by boiling water in a boiler, expands and flows through the turbine's blades, causing them to rotate. This rotational energy is then converted into mechanical work, which can be used to generate electricity or drive machinery. The efficiency and performance of the turbine depend significantly on the properties of the steam, including its pressure and temperature.
