Steam is the working fluid in the ideal Rankine cycle 12
Chapter 8, Problem 8.3(choose chapter or problem)
Steam is the working fluid in the ideal Rankine cycle 1–2– 3–4–1 and in the Carnot cycle 1–2–39–49–1 that both operate between pressures of 1.5 bar and 60 bar as shown in the T–s diagram in Fig. P8.3. Both cycles incorporate the steady flow devices shown in Fig. 8.2. For each cycle determine (a) the net power developed per unit mass of steam flowing, in kJ/kg, and (b) the thermal efficiency. Compare results and comment.
