A proposed steam power plant design consists of an ideal Rankine cycle with reheat and regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to an open feedwater heater while the remainder is reheated to T3 before entering Turbine 2. The condenser operates at P4. Saturated liquid exits the condenser and is fed to Pump 1. The outlet of Pump 1 is fed into the open feedwater heater. Saturated liquid exits the feedwater heater and is fed to Pump 2. All turbines and pumps are isentropic.
m1 (kg/s) = 50
P1 (Bar) = 160
T1 (oC) = 640
P2 (Bar) = 10
T3 (C) = 600
P4 (Bar) = 1
P5 (Bar) = 0.06
Required:
a. Determine the specific enthalpy (kJ/kg) at the inlet of turbine 1.
b. Determine the specific enthalpy (kJ/kg) at the exit of turbine 1.
c. Determine the specific enthalpy (kJ/kg) at the inlet of turbine 2 .
d. Determine the specific enthalpy (kJ/kg) at the exit of turbine 2.
e. Determine the specific enthalpy (kJ/kg) at the condenser exit.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
