Question

The compression ratio in an air-standard Otto cycle is 10. At the beginning of the compression stroke the pressure is 01 MPa and the temperature is 12 degree C. The combustion heat: transfer per unit mass of air is 1200 kJ/kg. (The specific internal energy at the end of the expansion process is u1=746. 44 kj/kg) Determine: Temperature at the end of each process of the cycle Thermal efficiency. Water is the. working fluid in an ideal Rankine power cycle with reheat Steam enters : the high-pressure turbine at 14MPa and 600 degree C and expands to 0. 7Mpa. Specific enthalpy at the inlet of the low-pressure turbine is 3350 kj/kg. Saturated vapor at 0. 008MPa. enter and saturated liquid exits the condenser. Determine: Thermal efficiency of this system; Back work ratio: Show the cycle on the T-s diagram;. How will the results of the cycle analysis change if we take into account irreversibility's in turbine and pump? Illustrate changes on the T-s diagram. Will the thermal efficiency increase or decrease?(A brief theoretical explanation is good, no calculations are necessary.) Consider an ideal vapore-compression refrigeration cycle operating between pressures of 0. 14 MPa (evaporator) and 0. 80 MPa (condenser). The flow rate of refrigerant R-134a is 0. 04 kg/s. Determine:
