Heat rate of a reheat turbine

Heat rate of a reheat turbine
= ( ( Main steam flow at ESV inlet x (Enthalpy of main steam - Enthalpy of feed water ) + ( Reheat steam flow x ( Enthalpy of hot reheat - Enthalpy of cold reheat ) ) ) / New power output in MW.

Steam turbine

Steam turbine shaft vibration is calculted as per ISO 7919.
