The TS diagram for the single-turbine Non-ideal Rankine Cycle (shown on the left) has been modified to allow for a process called 'reheat" (shown on the right). The reheat process requires a second turbine, and the addition of heat to the fluid between the first and second turbines. The reheat process occurs at an intermediate pressure (shown on the diagram as p mid), and occurs between state-2 and state-1b on the diagram, and usually raises the temperature of the fluid to a temperature named t mid. Therefore, state-lb usually has known properties (p-p mid, t- t_mid) in the superheated region. (I said usually" twice, because sometime we simply reheat the fluid to the 100% state) 1b 4 4s 2s 2bs' 2b 2s 2 Notes for Reheat: a) Since there are two turbines, the Rankine efficiency equation has two turbine work terms: (hl minus h2) and (hlb minus h2b) Since there are two places where heat is added to the fluid, the Rankine efficiency equation has two heat added terms: (hl minus h4) h2) b) and (hlb minus Problen Statement: a) Write a Rankine efficiency0 function will have 2 required inputs and 5 optional inputs, as shown below. The function will calculate and returm the efficiency of the non-ideal Rankine cycle, with (optional) reheat def Rankine eficiency(p_high, p_low, hirbine_efficiency-1.0, pump_efficiency-1.0) t_high-None, p_mid-None, tmid-None, If thigh is None, then assume that X1-100%.
