T 1: 500 C


Rankine cycle is a steam cycle used in thermal power plants. specific heat calculator This cycle; steam boiler, steam turbine, condenser (condenser), and I oluşur.çev four main components used in the pump, that is, work that fluid is water. specific heat calculator Is heated until it becomes specific heat calculator superheated steam at a constant pressure in the boiler water passes through the steam turbine loses pressure and temperature and to obtain mechanical work. Mechanical work obtained from the steam turbine is converted into electrical energy by the generator coupled to the turbine. Turbine from said wet steam then enters a condenser where it is converted into saturated liquid cooling at constant pressure. The saturated liquid is pumped down into the boiler, and the cycle repeats.
In an ideal Rankine cycle boiler 10 MPa and 500 C in the water, an isentropic expansion turbine 10 kPa pressure. Once the turbine specific heat calculator is condensed into water saturated water in the condenser is sent to the boiler with an isentropic pump.

2. The fluid exiting the turbine case is saturated zone states. Be the first to find the enthalpy value of this fluid corresponding to 10 kPa from saturated hall table S s and S b entropy values, dryness of the fluid is calculated.
X 3: 0
Amount of heat per unit time gains;
W pump = 2. (191.81- 201 899) = - 20 178 kW
These values of elements in the cycle under ideal conditions (isentropic), assuming that we have found. Stage pump turbine used in the cycle in real conditions is isentropic. Therefore actually need more power for the pump and the work becomes less obtained from the turbine.
