The piping system that delivers water to the second floor ofyour house, at an elevation of 16 feet from the ground, consists of22 feet of 0.75\" ID (ID = Internal Diameter) pipe followed by 16feet of 0.5\" ID pipe.  Calculate the minimum pressurerequired at the beginning of the piping system, located on groundlevel, for delivering water with a flowrate of 2.7 gallons perminute at atmospheric pressure on the second floor. Consider onlylosses at the constriction and major losses. The piping is copper,and has roughness of “drawn tubing”.
