Question

a)

b)

A steam turbine has 7 Ibm/min of steam entering at (200 psi, 600 degree F) and leaving at 1 psi quality of 90%. Draw the process on a T-v diagram Find the power generated by the turbine (Btu/s) In order to operate at partial load (not all the power calculated in #1 is needed), the steam will go through an expansion valve before it goes through the turbine. 7 Ibm/min of steam enters at state 1 (200 psi, 600F), goes through an expansion valve with the pressure dropping to 120 psi (state 2), and then travels through the turbine exiting at state 3 psi with a quality of 90%). Note that you can reuse the values from #1 for states 1 and 3. (don't show the same work again) Draw both processes on the same T-v diagram Find the power generated by the turbine (Btu/s)
