(11) For the Venturi meter shown in fig. 1, the deflection of the mercury in the U-tube is 0.35m. Determine the volume flow rate of water through the meter and the pressure difference between sections A & B if the head loss H between A & B is 0.2 m. (12) The diameter of a pipe bend is 300 mm at inlet and 150 mm at outlet, the flow is turned 120 in a vertical plane. The axis at inlet is horizontal and the center of the outlet section is 1.4m below the center of inlet section. The total volume of fluid contained in the bend is 0.085 m. Neglecting friction, find the magntide and direction of the net force exerted on the bend by water flowing through it at 0.23 m/sec if the inlet pressure is 140 kPa. B 0-5M A 15cm 30 CM Fig.1 Hg 035m
