solve and explain your answer

Consider a modification of the air-standard Otto cycle in which the isentropic compression and expansion processes are each replaced with polytropic processes having n = 1.35. The compression ratio is 8 for the modified cycle. At the beginning of compression, p, = 1 bar and T1 = 310 K. The maximum temperature during the cycle is 2200 K. Determine: (a) the heat transfer and work in KJ per kg of air for each process in the modified cycle. (b) the percent thermal efficiency. (c) the mean effective pressure, in bar. Part A Determine the heat transfer and work in KJ per kg of air for each process in the modified cycle. Note the air is the closed system. Process 1-2: Q 12 i KJ/kg W 12 = i KJ/kg Process 2-3: Q23 i KJ/kg W 23 i KJ/kg Process 3-4: Q34 W34 i KJ/kg KJ/kg Process 4-1: WAI i kJ/kg i KJ/ke
