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 700 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. a) Determine the pressure at the end of the heat-addition process in kPa. b)Determine the temperature at the end of the heat-addition process in K. c)Determine the net work output in kJ/kg d)The thermal efficiency e) Determine the mean effective pressure for the cycle in kPa.

1. (30 points) Classify the systems shown in the following figures. Each system is indicated by the dashed line. (By classification, we mean answering the questions like: is it homogeneous/nonhomogeneous?, is it closed or open?, is it adiabatic or not?, is it isolated or not?, does it have fixed or moving boundaries?) Explain your reasons. Otherwise, you'll get partial credit. gas gas liquid liquid a) b) c) a) Closed tank that contains some liquid and some gas at the same temperature. b) Closed tank that contains some liquid and some gas at different temperatures. The tank is thermally insulated. c) Thermally insulated condenser of a laboratory-scale distillation unit. Hot vapor flows through the center of the condenser while cold water flows on the outside, causing the vapor to condense.
