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.)
draw a free body diagram for each of the two situations. use the "radial" Newton's law to find the tension in the string at each of these situations.
Determine the temperature of the electric heater element and drawing of the temperature profile.
Find the final state inside the tank, A tank contains 2kg of nitrogen at 10K with a quality of 50%.Through a volume flow meter and valve, 0.5kg is now removed while the temperature remains constant.
In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.
Obtain a new solution, and determine whether any buckling constraints are active. If no buckling constraints are active for L = 10 in., re-run the analysis by increasing L , and estimate the value of L at which at least one buckling constraint b..
