示例1: openRankine
int openRankine(int np, void* p) {
double etap = 0.6; // pump isentropic efficiency
double etat = 0.8; // turbine isentropic efficiency
double phigh = 8.0e5; // high pressure
Water w;
// begin with water at 300 K, 1 atm
w.setState_TP(300.0, OneAtm);
saveState(w,"1");
// pump water to 0.8 MPa
w.setState_SP(s["1"], phigh);
saveState(w,"2s");
double h2 = (h["2s"] - h["1"])/etap + h["1"];
w.setState_HP(h2, phigh);
saveState(w,"2");
// heat to saturated vapor
w.setState_Psat(phigh, 1.0);
saveState(w,"3");
// expand to 1 atm
w.setState_SP(s["3"], OneAtm);
saveState(w,"4s");
double work_s = h["3"] - h["4s"];
double work = etat*work_s;
w.setState_HP(h["3"] - work, OneAtm);

printStates();
double heat_in = h["3"] - h["2"];
