For a Rankine cycle, increasing maximum temperature while holding all other parameters constant will allow an engineer to make the following statements Group of answer choices Quality at the turbine exit will decrease increasing liquid water content and causing turbine erosion. Quality at the turbine exit will increase and improve turbine durability. Increasing maximum temperature increases the average temperarture at which heat is added and will increase thermal efficiency Increasing maximum tempearture will decrease required mass flow rate for a specified power output.
