1.first of all display – Rankine cycle simulator, using disp command.
2.Now write rankine cycle’s all process using fprintf command.
3.Assign the values of given parameters ,Turbine inlet pressure(p_1) = 30 bar, Turbine inlet temperature(t_1) = 400 deg celsius ,Turbine outlet pressure(p_2) = 0.05 bar.
4.Put XSteam. m file in same directory and call the XSteam function with suitable arguments to find the values of enthalpy, entropy for state 1.
5.Use fprintf command to print values of variables we found. Repeat the procedure for all other states to find unknows.
6.Now apply a for loop to find values of enthalpy and entropy at saturated temperature and store them into variables.
7.Find net work output and back work ratio with suitable formulas.
8.Plot the T-s and h-s diagram using all the value we have found in different states and give proper x and y label and add state number by text command.
9.Plot saturation line using the values we have found by for loop
Rankine cycle simulator
1-2 is the isentropic expansion process
2-3 is the constant pressure heat rejection process
3-4 is the isentropic compression process
4-1 is the constant pressure heat addition process
