Question 1: Superheated steam enters a turbine at 7 MPa, 550°C, and exits at 150kPa. a) Draw the system. b) If the process is reversible adiabatic (isentropic), find the final temperature (T2s), the final enthalpy (h2s) of the steam, and do the energy balance to calculate the turbine work (Ws). c) Using entropy balance, show that Sgen for the above process is 0. d) If the isentropic efficiency is 85%, find the actual final temperature (T2a) and calculate Sgen? e) Plot process (b) and (d) on a Ts diagram with proper labelling.

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.
