Aflowrate measuring device is installed in a horizontal pipe through which water is flowing. a u-tube manometer is connected to the pipe through pressure taps located 3 in. on either side of the device. the gage fluid in the manometer has a specific weight of 112 lb/ft3. determine the differential reading of the manometer corresponding to a pressure drop between the taps of 0.5 lb/in2.

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?
