The air of specific weight 12 N/m3 flows in a converging tube with the pitot tube attached to the walls of two sections. The stagnation point of the pitot tube is positioned at the center of the 100-mm-diameter section facing the flowing air and the other open end of the tube is tapped into the walls of the 60-mm-diameter section. The manometer liquid is benzene(s=0.877). Compute the flow rate if (6.1) losses are neglected; (b) losses are 0.5 times the velocity head in the smaller section.
