Required information Problem 09.034 - Ideal Otto Cycle with Variable Specific Heats - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS 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 760 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. Problem 09.034.a - State After Heat Addition in Variable Heat Capacity Ideal Otto Cycle Determine the pressure and temperature at the end of the heat-addition process. (You must provide an answer before moving on to the next part.) 20158₂

The compression ratio of an Otto cycle as shown in the figure below is VA/VB = 9.00. At the beginning A of the compression process, 505 cm3 of gas is at 115 kPa and 20.0°C. At the beginning of the adiabatic expansion, the temperature is TC = 725°C. Model the working fluid as an ideal gas with ? = 1.40.

An air standard Otto cycle at the start of the isentropic compression has P₁ = 100 kPa and T₁ = 27°C. The compression ratio is 10 and during the heat addition process 1000 kJ/kg are supplied. Using the cold air standard analysis method, the net work for this cycle is most nearly equal to: A. 960 kJ/kg B. 900 kJ/kg C. 602 kJ/kg D. 333 kJ/kg E. Cannot be determined with the given information

Consider a Diesel cycle with cold-air-standard assumptions, and compression ratio of 21. The temperature and pressure at the beginning of the compression process are 320K and 120kPa respectively. The cutoff ratio for this cycle is 1.8. The isentropic efficiency of the compression and expansion process are 85%. Determine the temperature and pressure at the end of each process of the cycle, the heat transfer per unit mass in and out of the air; qin and qout, thermal efficiency of the cycle, and the mean effective pressure of the cycle.
