In a 4-stroke ideal diesel cycle; The cylinder volume is 0.96 liters when the piston is in bottom dead center, and the cylinder volume is 0.06 liters when it is in top dead center. At the beginning of compression, the temperature is T1 = 336 K, P1 = 98 kPa. 1.64 kJ / cycle heat is released as a result of combustion. The mechanical efficiency of the 6-cylinder engine operating at n = 1860 rpm is m = 0.84. Since Cv = 716.5 J / kg K, Cp = 1003.5 J / kg K, R = 287.13 J / kg K; a) Thermodynamic values at the cycle points, b) Effective power of the engine.
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.
