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.

A power plant operating on an ideal Rankine cycle has steam entering theturbine at 500°C and 2 MPa. If the steam enters the pump at 10 kPa, calculate the thermal efficiency with pump work included, the thermal efficiency neglecting pump work, and the percentage error in efficiency neglectingpump work.

! 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.) The pressure at the end of the heat-addition process is 3915.8 kPa. The temperature at the end of the heat-addition process is 1647.7 K.
