Finding exit area of steam turbine
WebThe adiabatic expansion of steam in a turbine is most conveniently represented on the enthalpy-entropy (H-S) Mollier diagram. Point 1 = turbine inlet, Point 2 = low-pressure exhaust for process heating … WebDec 15, 2006 · A larger exit area results in lower steam exit velocities and thereby reduces the kinetic energy of the steam leaving the turbine. The result is higher overall steam turbine efficiency.
