An undeveloped site occupies a lot that is 850 by 250 feet. the top of the lot is 15 feet higher than the bottom. the town would like to develop the lot into a neighborhood business district. (a) calculate how much runoff the town would need to accommodate if they wish to plan for the100-year storm using the idf curve provided by isws bulletin 70 from 1989. (b) determine the revised runoff using the idf curve provided in isws bulletin 70 revised in 2019.

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?
