Thermal Efficiency of Steam Turbine

2  · The thermal efficiency, η th, represents the fraction of heat, Q H, that is converted to work.Since energy is conserved according to the first law of thermodynamics and energy cannot be be converted to work completely, the heat input, Q H, must equal the work done, W, plus the heat that must be dissipated as waste heat Q C into the environment. Therefore we can rewrite the formula for thermal
