An ideal Brayton cycle has a pressure ratio of 8. At the beginning of the compression process, air is at 300 K. If Tmax in the cycle is 1200 K, determine the temperature of air, in K, at the beginning of heat exchange processes.

! 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.

Assuming a compression ignition engine having a cut-off ratio of 2 and a compression ratio of 20. Before the compression stroke, air is at 100kPa, 20°C and a volume of 500 cm³. Determine (in kPa) the mean effective pressure of the cycle

Hello Sir,Good Night.I have a question in my homework related thermodynamics lesson.The following below is my question. Please advice, thank you

A gas turbine cycle has a single compression with pressure ratio of 18, and has isentropic efficiency of 80%. The air enters the compressor at 95 kPa, 27°C. The cycle has two stages of expansion, with a reheat between the stages. Air enters the first stage at 1300°C and exits the reheat at 1050°C. The cycle also includes a regenerator with an effectiveness of 76%.Calculate the compressor work,turbine work and the thermal efficiency
