A (6 m) long pipe is inclined at an angle of 20 with the horizontal. The smaller section of the pipe which is at lower level is of (100 mm) diameter and the larger section of the pipe is of (300 mm) diameter as shown in Fig. bellow. If the pipe is uniformly tapering and the velocity of water at the smaller section is (1.8 m/s), determine the difference of pressures between the two sections.
