An ideal Brighton cycle has a pressure ratio of 15. The inlet air to the compressor is assumed to have a pressure of 100 kPa and a temperature of 340, and in a turbine inlet with a temperature of 1300. Assuming specific heat variables (using the relationships of relative pressure, relative volume and standard air table) for air, Use a heat recovery regenerator with 72% efficiency. It is desirable: • Temperature unit K • Compressors and turbines are isentropic. That is, they have 100% thermal efficiency. A) Draw approximate diagrams of T-s and P-v, calculate the pressure and temperature of the four points of the cycle B) Net output work C) Cycle after cycle ratio D) Thermal efficiency of the cycle

Stress transformation

The term stress indicates the measure of internal forces that develop due to an external force's application on an object. When a specific external force is applied to an object, internal stress generates in the material. The value of stress can obtain by taking the ratio of the externally applied force and cross-sectional area of the object. There are different types of stress depending on the type of external force.
