Pressure Changers A piping system is to be designed to transport toluene in a chemical plant. The fluid will enter the piping system at a rate of 10 gallons per minute (gpm),20C and 1atm. You are asked to choose the best pump for a piping system consisting of: 20 -ft horizontal pipe, long radius 90 bend, 20 -ft vertical pipe, long radius 90 bend, open gate valve, 10 -ft horizontal pipe, PUMP, 10-ft horizontal pipe, open gate valve, long radius 45 bend, 100 -ft vertical pipe. The pipes are made from commercial steel (schedule 40, 1-in diameter). All fittings are flanged. a) Choose the most suitable pump for the process by comparing at least two pumps from the Fristam Pumps catalog and corresponding pump curves available in the Moodle course page. Comment on the criteria you used to choose the pump, including total head, outlet pressure, power requirements, efficiency, NPSH, etc. (Hint: you can start by estimating the head required to maintain fluid flow in the process and using this information to read the pump performance curves in the catalog). b) For the selected pump, what are the conditions required to avoid cavitation (e.g., minimum operating pump inlet pressure)? c) For the selected pump, what is the effect of increasing flow rate in the pump efficiency? d) You are also asked to consider an increase in fluid flow rate to 40gpm. Will your design be suitable for transporting toluene at this flow rate? Why? Please discuss. If needed, propose an alternative design (e.g., different pump, impeller diameter, pipe diameter, pump placement, etc.) that could be used for this purpose. Run a separate simulation for these new conditions and justify your choices
