Power density relative to its maximum value at and versus Newtonian heat transfer law efficiency ( ). The plots represent values of in the 1–10 range. The ratio between the temperatures of the reservoirs, is , a typical value for a Rankine cycle (for the steam turbine working between 600 K and 300 K).
