Answer Happy

There are multiple parts per question, please be as clear as
possible.
3: Consider the Rankine power cycle using vapor and liquid. a: Draw the T-s property diagram of the Carnot Vapor Cycle and explain what kind of problem the Carnot Vapor Cycle has in each process explicitly. b: Draw a T-s diagram for the ideal Rankine cycle and label each process explicitly. Write down the thermal efficiency in terms of enthalpy. c: There is a method to increase the boiler pressure in order to improve the efficiency of the ideal Rankine cycle. Explain its advantages and disadvantages in terms of the property diagram explicitly. d: Name the gas power cycle which uses the same four processes in its cycle and draw the T-s diagram and the P-v diagram for the gas power cycle.
