One approach to solving cycle problems of this nature is to work your way around the cycle until you have evaluated all the properties to complete the table shown above. Then, you can go back and apply the 1st Law to each process in the cycle to evaluate Q and W s as need. That is the approach I will take. The Simple Rankine Cycle 9-7C The four processes that make up the simple ideal cycle are (1) Isentropic compression in a pump, (2) P = constant heat addition in a boiler, (3) Isentropic expansion in a turbine, and (4) P = constant heat rejection in a condenser. 9-8C …

Chapter 8-1 Chapter 8: Gas Power Cycles Our study of gas power cycles will involve the study of those heat engines in which the working fluid remains in the gaseous state throughout the cycle. the efficiency of the Rankine cycle have been ana-lyzed. Thermal power plant based on a Rankine cycle In a simple Rankine cycle, steam is used as the working fluid, generated from saturated liquid water (feed-water). This saturated steam flows through the turbine, where its internal energy is converted into mechanical work to run an electricity

Comment: This cycle is the same as the Rankine cycle 4 processes, but it takes place in the ideal gas region of states. The last process does not exist in the real gas turbine which is an open cycle.
