An isentropic turbine accepts steam at an initial temperature and pressure of 500 c and 7 mpa, and rejects steam at a final pressure of 2.34 kpa. a. what is the state of the steam at the turbine exit? give x, v, u, h and s. b. how much work does the turbine produce per kg of steam? c. what is the power output of the turbine at a steam flow rate of 1 kg/s? d. if electricity can be sold a 0.025 dollars per kwhr what is the value of the electrical power this turbine can produce in a day?

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?
