imagine a pipe that splits into a Y where each upper branch of the Y is at a 45 degree angle from the main stem. The inflow is through the main stem base of the Y, where the pipe is0.3 m diameter and has an upstream pressure of 380 kPa. One of the branches of the Y is a 0.1m diameter pipe where the flow exits to atmospheric pressure. The other branch of the Y is a 0.2m diameter pipe where the flow goes into other piping at a pressure of 200 kPa. Determine the candy reaction forces. You may assume the flow is steady state and neglect shear stress and weight.

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?
