Need help solving for part b, c, and d please
An ideal Otto cycle has a compression ratio of 9. At the beginning of the compression process, P, = 90 kPa, T1 = 27 °C, and V1 = 0.004 m? The maximum cycle temperature is 1500 K. Using constant room-temperature specific heats, (a) calculate the heat rejection for each repetition of the cycle, in kJ (enter numerical value only without units). Answer: 0.9686 Check Correct Marks for this submission: 3.0/3.0. (previous problem continued) ... (b) Calculate the net work production for each repetition of the cycle, in kJ (enter numerical value only without units). Answer: 2.28 Check Partially correct Marks for this submission: 1.0/3.0.
(continued) ... (c) Calculate the thermal efficiency for this cycle. Submit your answer as a decimal number (not a percentage). Answer: 58.4 x Check Incorrect Marks for this submission: 0.0/3.0. (continued) ... (d) Calculate the mean effective pressure for this cycle, in kPa (enter numerical value only without units). Answer: 1569.315 Check Partially correct Marks for this submission: 1.0/3.0.
