An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg.K. Determine the net work output. (You must provide an answer before moving on to the next part.) The net work output is 0 kJ/kg.
An ideal gas turbine cycle consisting of 2 stages of compression and 2 stages of expansion has an overall pressure ratio of 9. Air enters the compressors at the temperature of 320 K while, being intercooled between the stages. Air enters the first compressor at 100 kPa and the pressure ratio of each of the compressors are selected in a way that minimizes the total power input for the compressors. The high-pressure turbine (First one) drives the compressors and the low-pressure one produces power output. The compressors and both the high-pressure and low-pressure turbines can be assumed ideal. To increase the efficiency of the cycle a regenerator with effectiveness of 85% is used to recover some heat from the exhaust of the second turbine. In this cycle, air with the temperature of 1400 K enters the first turbine. After expansion in the first turbine, air is reheated to the same temperature at the inlet of the first turbine (1400 K). You can consider constant specific heats of c,1.005…
An ideal Otto cycle has a compression ratio of 6. At the beginning of the compression process, air is at 100 kPa and 27°C. If the temperature of the air at the end of the expansion process is 450°C, determine the maximum temperature, in K (Kelvin), in the cycle. (Apply cold-air-standard assumptions: constant specific heat)
A four-cylinder, two-stroke 2.4-L diesel engine that operates on an ideal Diesel cycle has a compression ratio of 22 and a cutoff ratio of 1.8. Air is at 70°C and 97 kPa at the beginning of the compression process. Using the cold-airstandard assumptions, determine how much power the engine will deliver at 4250 rpm.
An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg-K. Determine the mean effective pressure for the cycle. The mean effective pressure for the cycle is 0 kPa.
An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 100 kPa and 17°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Draw the cycle on p-v and T-s and determine the thermal efficiency.
An ideal dual cycle has a compression ratio of 18. At the beginning of the compression process, air is at 100 kPa and 20 o C, while it is at 1900 o C at the end of the heat-addition processes. If the amount of heat added to air is 1000 kJ/kg, determine the following: 1- The amount of heat added at constant pressure, 2- The amount of heat added at constant volume, 3- The net work done by the cycle, 4- The thermal efficiency of the cycle, and 5- The mean effective pressure.

Compare the thermal efficiency of a two-stage gas turbine with regeneration, reheating, and intercooling to that of a three-stage gas turbine with the same equipment when the maximum cycle temperature is 800°C.
Hello Sir,Good Night.I have a question in my homework related thermodynamics lesson.The following below is my question. Please advice, thank you
Instead, assume variable specific heat An ideal Otto cycle has a compression ratio of 8. Atthe beginning of the compression process, air is at 95 kPaand 278C, and 750 kJ/kg of heat is transferred to air dur-ing the constant-volume heat-addition process. Taking intoaccount the variation of specific heats with temperature,determine (a) the pressure and temperature at the end ofthe heat-addition process, (b) the net work output, (c) thethermal efficiency, and (d) the mean effective pressure forthe cycle.
