A single-acting compressor completes one compression cycle with one revolution of the crank. And for a double-acting compressor completes two compression cycles with one revolution of the crank. 0.013 m³ S Gas is compressed in a reciprocating compressor from 1 bar to 6 bar. The free air delivery is The clearance ratio is 0.05. The expansion process of the cycle follows the law of pv12 = C. The crank speed is 360 rev/min. Critically evaluate volumetric efficiency formula for a reciprocating compressor.
Two ideal Brayton cycles (see Figure below) have the same inlet temperature and the same maximum temperature of the turbine inlet. Brayton Cycle A has a higher compression ratio than Cycle B. Which of the following statements is true about the cycles? Cycle A has a higher thermal efficiency and Cycle B has a higher work net for a given mass flow rate. Cycle B has a higher thermal efficiency and a higher work net for a given mass flow rate. Since the temperatures are the same the efficiencies and work net are also the same. Cycle A has a higher work net for a given mass flow rate and Cycle B has a higher thermal efficiency. Cycle A has a higher thermal efficiency and a higher work net for a given mass flow rate.

3. What are the four major accessories of a Rankine Cycle? Define each.
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.
