Design the most efficient screw pump for the following system: minimum sewage elevation in interceptor of $112\mathrm{.}60m,$ maximum sewage elevation in interceptor of $112\mathrm{.}80m,$ discharge elevation to stilling well of $116\mathrm{.}40m,$ an average design flow of $8,600\frac{m^3}{d},$ peaking factor for peak hour of $2\mathrm{.}8$ and minimum factor of $0\mathrm{.}49.$ Use typical screw pump selection table $(20-1).$

Using a spreadsheet you developed, design a bar rack channel using an inlet channel width of $0\mathrm{.}8m,$ slope of $0\mathrm{.}04\%$ and the discharge values given in Problem $4.$ Assume an approach velocity at average flow rate $0\mathrm{.}4\frac{m}{s}$; approach velocity at peak hour flow rate at design capacity $0\mathrm{.}9\frac{m}{s}$; two channels will be provided for redundancy, but one channel must handle the flow for the peak hydraulic flow rate. Use a freeboard of $0\mathrm{.}6m.[$note $-$ the problem requires multiple PDF view on GradeScope of the formula, numerical data and any solver function used$]$ NOTE: GradeScope only accepts PDFs$,$ you will need to submit your working spreadsheet in CANVAS for full credit.
