All of the calculations are <br /> based on the site data you have provided to us and on nominal engineering values <br /> for the physical parameters. <br /> All of the calculations are based on standard engineering practice. We use <br /> approaches in a manner similar to the protocols presented in the PEI/RP 100-17 <br /> manual to calculate the underground tank Buoyancy Safety Factors. <br /> It is the tank owner's responsibility to determine the suitability and applicability of <br /> installation. Our sole responsibility in any installation is as stated in our Limited <br /> Warranty. <br /> Our calculations show that, given the installation parameters that you have provided <br /> to us (calculated with the tank empty, burial depth of 5 feet, the water table at the <br /> same elevation as the finished grade, and anchored with factory-supplied deadmen) <br /> the Buoyancy Safety Factors are as follows: <br /> Tank Buoyancy Safety Factor <br /> 24k x 6k-gallon Double-Wall MCT 1.44:1 <br /> 6k x 20k x 6k-gallon Double-Wall MCT 1.39:1 <br /> We recommend a minimum Buoyancy Safety Factor of 1.20:1. I have included <br /> copies of the worksheets for your files. <br /> If we can be of additional assistance, please feel free to contact us. <br /> Since,/ ..rely, <br /> t v�___ <br /> �4 <br /> Tejinder Singh <br /> Applications Engineer <br /> Attachment - 2 <br /> 7901 Xerxes Avenue South • Minneapolis • Minnesota • United States • 55431-1288 <br /> Ph: 952-887-1890 • Fax: 952-887-1870 •Web: www.xerxes.com <br />
