Air enters the compressor of an ideal air-standard Brayton cycle at 110 kPa, 289 K, with a volumetric flow rate of 5 m3/s. The compressor pressure ratio is 12:1. The turbine inlet temperature is 1567 K. Take the gas constant as 289 J/kg.K and Specific heat at constant pressure and constant volume for air as 1.004 kJ/kg K and 0.708 kJ/kg K respectively. Calculate the net power developed to two decimal places and include the correct SI unit symbol.
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.
