Apumper truck is to deliver 1.5 ft^3/s of flow to a maximum elevation of 60 ft above the fire hydrant. the pressure at the 4 inch diameter outlet of the hydrant is 10 psi. if the head loss amounts to one velocity head, how much power the pump should add to the water?

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?
