Textbook Question

Chapter 9.12, Problem 62P

The compression ratio of an ideal dual cycle is 14. Air is at 100 kPa and 300 K at the beginning of the compression process and at 2200 K at the end of the heat-addition process. Heat transfer to air takes place partly at constant volume and partly at constant pressure, and it amounts to 1520.4 kJ/kg. Assuming variable specific heats for air, determine (a) the fraction of heat transferred at constant volume and (b) the thermal efficiency of the cycle.

An Otto cycle uses air as its working fluid. The compression ratio of the cycle is 10. 1,800 kJ/kg of heat is added during the heat addition process. If the temperature and pressure at the end of compression are 444C and 2,168Kpa. Assume constant specific heats for the analysis, determine (a) the temperature and pressure at the end of each process, (b) the thermal efficiency of the process (c) the net Work of the cycle (d)mean effective pressure of the cycle.

Consider an air-standard Carnot cycle in which the overall ideal thermal efficiency is 75% and the heat supplied is 50 kJ/kg. The pressure and specific volume at the end of isothermal expansion process is 600kPa and 0.5m3/kg, respectively. Determine (a) the maximum and minimum temperature of the cycle in K, (b) the specific volume, in m3/kg and the pressure, in kPa at the beginning of heat addition process, and (c) the net work developed in kJ/kg. Show the P-V and T-s diagram.

A power cycle operates between two thermal reservoirs at 300 K and 800 K. The working fluid of the cycle is air, which can be considered to be an ideal gas. Specific heats are not assumed to be constant. An inventor claims that for a heat input of 250 kJ, the net work from the cycle is 80 kJ. The work generating component in the cycle is a reversible, steady state turbine. The inlet pressure and temperature are 1000 kPa and 600 K and the exit temperature is 550 K. The turbine receives 150 kJ/kg of heat from the high temperature reservoir and loses 10 kJ/kg of heat to the ambient at 298 K. (a) Prove whether or not the overall cycle is possible using second law arguments. (b) determine the work done by the turbine [kJ/kg]
