The efficiency of a single-stage steam turbine varies from 40% to 50% depending on factors such as its design, operating conditions, and steam quality. Achieving higher efficiency typically involves optimizing blade design, using higher steam pressures and temperatures, and reducing mechanical losses such as friction and leakage. Engineers focus on these features to maximize efficiency for specific applications, ensuring that the turbine uses the energy from the steam efficiently.
