Problem 1: Part of a Modified Rankine Cycle Used in Nuclear Plants A portion of saturated steam (stream 41 ) at P1=60 bar is expanded into a High Pressure (HP) steam condensing turbine K-101 to an exhaust pressure of P4=11.5 bar . The discharge of the HP turbine (stream $4 is directed to a moisture separator to remove the liquid water. The vapor from the HP turbine discharge (stream S6) is reheated to T8=250C in the heat exchanger E-101 with a slip stream $3 from the main steam supply line $1. A schematic of this process is shown below. Assume that the steam turbine efficiency is =80% 1. Calculate the steam flow rate(in MMSCFD) of stream $2 required to produce 250MW of power from the high pressure turbine 2. Calculate the steam flow rate(in MMSCFD) of stream $3 required to reheat the vapor exhaust of the high pressure turbine to 250C 3. Calculate the steam flow rate(in MMSCFD) of stream $1 4. Calculate the temperature(in deg C) of stream 55 5. Calculate the temperature(in deg C) of stream S7
