Otto Cycle Numerical – 5 | Air Standard Cycles | Applied Thermodynamics

Air Standard Cycles | Otto Cycle Numerical – 5 | Engineering Thermodynamics a) show that the compression ratio for the maximum work to be done per kg in an Otto cycle between upper and lower limits of absolute temperatures T3 and T1 is given by r =r =[ 〖T_3/(T_1 )]〗^(1/(2 ( γ-1) )) b) Determine the air standard efficiency of the cycle when the cycle develops maximum work with the temperature limits of 310 K and 1220 K and working fluid is air. What will be the percentage change in the efficiency if helium is used as working fluid instead of air? The cycle operates between the same temperature limits for maximum work development. Take γ for helium as 1.66 In this lecture, we solve the numerical problem on the Otto Cycle using the principles of Air Standard Cycles. The solution is explained step by step, making it easy to understand the application of thermodynamic equations and cycle analysis. 📚 Topics Covered Otto Cycle Numerical – 5 Air Standard Assumptions Compression Ratio Thermal Efficiency Heat Supplied and Heat Rejected Net Work Output State Point Calculations Ideal Gas Relations Exam-Oriented Problem Solving This lecture is helpful for B.E./B.Tech Mechanical Engineering, Diploma Mechanical Engineering, GATE, and other competitive examinations.
