1. steam flows steadily through an adiabatic turbine. the inlet conditions of the steam are 6 mpa, 400°c, and 70 m/s, and the exit conditions are 45 kpa, 92 percent quality, and 50 m/s. the mass flow rate of the steam is 20 kg/s. determine: a. the change in the specific kinetic energy, in kj/kg. b. the power output, in mw. c. the turbine inlet area, in cm2.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
