In the figure below, water (RD = 1) flows in a pipe of diameter of 100 mm at point 1 and 50 mm at point 2. Points 1 and 2 are connected to a manometer of mercury (RD =13.6). If losses are neglected, determine the values of the velocities Vị and v2 Recalculate the velocities considering that the losses are 0.5 m
