Asimple vapor compression refrigeration system uses r-22 as the working fluid. the evaporator pressure is 3 bar and the condenser pressure is 20 bar. the cooling load is 225 tons, the refrigerant exits the evaporator at 0 c and it exits the compressor at 160°c. (1 ton 3.517 kw). 2. a. plot and label all 5 points on the provided p-h diagram. b. determine the power input to the compressor, in kw. c. determine the rate of heat rejection from the condenser, in kw. d. determine the cop of the system. e. determine the compressor efficiency

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?
