Asteam turbine has isentropic efficiency of 0.8. isentropically, it is supposed to deliver work of 100 kw. what is the actual work delivered by the turbine? a heat pump has a cop of 2.2. it takes 5 kw electric power. what is the heat delivery rate to the room being heated in kw? heat pump is used for winter heating of a room. a refrigerator takes 5 kw electric power. it extracts 3 kw of heat from the space being cooled a. what is the heat delivery rate to the surroundings in kw? b. what is the cop of the refrigerator?

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?
