A turbine salesman makes the following claim for one of his products: Steam enters a steady-flow adiabatic turbine at 4 MPa, 600 °C with negligible velocity and exhausts at 200 kPa with a velocity of 180 m/s. The flow rate is 2.2 kg/s and the turbine power is 2 MW.
a. If the turbine operated as described by the salesman, what would the temperature of the exhaust steam be?
b. Could the salesman's claim be valid? Explain and justify your response. (Hint: look at the Clausius Inequality.)
Sketch the frequency response of the system. Overlay the frequency spectrum of the excitation and as you start the system up, increasing Ω from 0 to 60 rpm, what speeds are most likely to excite large amplitude response? Why?
