3. liquid toluene, a current line along 1% of St 40 steel it is carried by pipe at 35RCd1 piece 450 in transport line elbow, la T (tee) connection and 1 full open angle there is an angle valve.alFlat pipe inithe system its length is 20 m. Entry and exit points of the pipeline 2.5 m height difference between (less) and pressure the difference (- AP) is 1.3 atm, so the toluene in the pipe is linear calculate the speed (V).
