boiler circulating cooling water

Thermodynamics: An Engineering Approach [9th ed

Therefore, the volume V, the mass m, and the total energy content E of the control volume remain constant during a steady-flow process (Fig. 1–33). Steady-flow conditions can be closely approximated by devices that are intended for continuous operation such as turbines, pumps, boilers, 17 CHAPTER 1
