Your team was selected to design a deionized (DI) water piping system for the student's unit ops lab. A 320 gallon storage tank re-circulates DI water throughout the lab. The tank has a diameter of 3ft. The water is pumped through the bottom of the tank and through a series of filters and polish beds to achieve a water resistivity of 18. The water then flows through a series of 5 valves. The head loss of these three units is reported by the manufacturer in terms of pressure drop. The total line length is 500ft. 80 feet of the DI water loop requires that the water flow at a minimum velocity of 12ft/s. The remaining 420 ft has a minimum water velocity requirement of 7ft/s. A schematic of the piping system and the pressure drops associated with the filters and valves is shown below. The required flow rate through the system is 35 to 40 gpm (gallons per minute). 10psi 6psi 2psi Polish Tank Filter Filter Bed XXXXX Vmin = 7ft/s 5.5 psi/valve Vmin = 12ft/s You are to submit a suggested system based upon the following criteria: Piping material: Your analysis should compare a minimum of two different types of piping material suitable for a DI water system in a unit ops lab. Pipe size (keep between 0.5 inches to 3 inches and use only schedule sized piping). Pump size. Your analysis should include the expected performance of your design and the overall estimated cost. Please supply references for all costs associated with the system analysis. The results section of your report should summarize all components of your teams analysis. Your analysis should investigate all types of piping materials. Your discussion should explain your selection of a specific material. Remember, mechanical energy performance is not the only metric that material selection is based upon.
