Consider now a turbine(Q=0) that operates with
N2 steam with T1 = 753.15K and P1 = 6 bar and P2 = 1 bar. The
efficiency is 80% and the molar flowrate is (note not mass flow
rate) is 200 mol/s. The inlet velocity is 30 m/s and the exit
velocity is 120 m/s. The inlet is 6 m above the base of the turbine
and the exit is 2 m above the base.
a. Determine the output of the turbine with units.
b. what is the exhaust temperature and quality (if saturated) for 100% efficiency?
c. What is the output temperature and quality (if saturated) for the given(80%) efficiency?
d. What are the enthalpy and entropy for the 80% efficiency of the turbine?
