1 a steam turbine receives steam at 250 psia and 900degf, Ask an Expert

Engineering

1. A steam turbine receives steam at 250. psia and 900.°F and exhausts it at 20.0 psia. The turbine is adiabatic and does the work of 190.4 Btu/lbm of steam flowing. Find the entropy production per lbm of steam flowing.

2. What mass flow rate is required to produce 75.0 kW from a steam turbine with inlet conditions of 2.00 MPa, 900.°C and exit conditions of 0.100 MPa, 200.°C if the turbine is reversible but not adiabatic? The heat transfer from the turbine occurs at a surface temperature of 50.0°C. Neglect any changes in kinetic and potential energy.
