An incompressible liquid (specific gravity = 0.7) is being transported along a horizontal, galvanized iron cylindrical pipe (actual inside diameter = 7.5 cm). At a volumetric flow rate of 4.5 L/s, two pressure gauges that are located 100 m apart along the length of the pipe indicate a pressure differential of 12.1 kPa.
