QUESTION 7 15 points Save Answer Steam flows through the turbine and heat exchanger network shown below at steady state. Stray heat transfer and kinetic and potential energy effects can be ignored. Using the state data provided, For 5 points, determine the isentropic efficiency of Turbine 1 (at left) as a decimal For 5 points, determine the work output of Turbine 2 (W_2/m_A at right) in kJ/kg steam For 5 points, determine the rate of entropy production within the heat exchanger in kJ/kg K of steam (you may use either mass basis) You must type your responses into the box, AND you must include calculations to support your results in your uploaded response file. w w Turbine 1 Turbine n, twwww www STATE DATA for SYSTEM P = 30 bar T = 700°C W/m. = 430 kJ/kg P2 = 7 bar P, = 7 bar T3 = 600°C PA = 0.06 bar N2 = 0.8 Ps = 20 bar T5 = 700°C Pe = 20 bar To = 600°C mg = m 2 Heat exchanger 5 тв
