A piping system is to be installed at place where the pump will transfer the fluid from tank A to tank B. There are two suggested piping designs available to carry the fluid efficiently. Compute and determine which of the available piping arrangement will experience the less pumping powerwith given flow conditions. Discuss the results.
Flow conditions are same for both type of designs and given as: Pipe material: stainless steel Volume flow rate: 40 L/sec Assume the working fluid is water at standard atmosphere temperature and both tanks areopen to atmosphere. Pipe inlet is sharp-edged and bends are sharped without vanes. Elevations are as ?? = ?? ? and ?? = ?? ?
