Low-Pressure Steam and Hot Water Heating Systems. Hot water boilers heat and circulate water at approximately 200°F. Steam heating boilers are used to generate steam at low pressures, such as 15 psig. Generally, these two basic heating systems are treated as closed systems, because makeup requirements are usually very low.

Steam enters a turbine operating at steady state with a mass flow rate of 1.5 kg/s. At the inlet, the pressure is 6 MPa, the temperature is 500 o C, and the velocity is 20 m/s.
