Problem 1) Steam at 10 bar and 330°C is fed to an adiabatic
turbine at a mass flow rate of m = 5kg /s • . The output stream is
saturated steam at 1.1 bar. The inlet steam flows through a 15 cm
diameter pipe and the exit steam discharges through a 20 cm

Thermodynamics
If you get a number from a table can you please show me a
picture of where you got it from because that's what i'm mainly
confused about.
1. Steam enters an insulated turbine at 100 bar,
400oC. At the exit, the pressure and quality are 200 kPa
and 0.54, respectively. Determine the power produced (kW) by the
turbine if the mass flow rate is 2.09 kg/s. (ans= 2,931.8)
2. Steam
enters a turbine at 8000 kPa, 440oC.
