Question: Steam enters the turbine of a Rankine cycle at 16 Mpa, 560 degree C. The condenser pressure is 8 kPa. The turbine and pump each have isentropic efficiencies of 100%, and the mass flow.

Question: Steam enters the turbine of a steam power plant that operates on a simple ideal Rankine cycle at a pressure of 6 MPa, and it leaves as a saturated vapor at 7.5 kPa.

A combined seperating and throttling calorimeter was used to determined the dryness fraction of steam flowing through a steam main at a pressure of 900kPa. The pressure and temperature after throttling were 100kPa and 110C. asked by Kay on December 7, 2010.

According to the problem, you have to relate the enthalpy change with the change in pressure (from 1 MPa to 2 MPa) at constant temperature (of 200 deg C) in prob (a) and then to relate the change in internal energy with the change in pressure (f.

VIII) A surface condenser is designed to handle 9000 kg of steam per hour. The steam enters at 0.06 bar absolute and dryness fraction is 0.88. The condensate leaves at the corresponding saturation temperature. The pressure is constant throughout the condenser.

In practical designs, the dryness fraction at the turbine exhaust of 0.88 is aimed at but almost impossible to achieve. For example, when the steam enters the turbine at 160 bar absolute and 600C (superheated steam, saturation temperature is only 345.75C), after isentropic expansion to 0.04 bar absolute, the dryness fraction is 0.772.
